Run One Circuit, Protect Two Locations.
Stop over-complicating your roof layout. The Drexan T-Connection Kit is the secret weapon used by professional installers like Eric Wimmer to create efficient, high-performance heat cable systems. Instead of running multiple long power leads back to a junction box, this kit allows you to “T-off” a single line of cable—sending heat in two different directions from one central point.
Why Professionals Use the T-Connection:
-
Complex Roof Layouts: Perfect for “Y” junctions where two valleys meet, or when you need to send one line down a gutter and another up a dormer.
-
Reduce Electrical Loads: By splitting a single circuit, you maximize the use of your existing breaker capacity without needing to install additional power points.
-
Clean, Low-Profile Install: Eliminates “cable clutter.” No more redundant lines of cable running side-by-side just to reach a new area.
-
Professional Reliability: This isn’t a “twist-and-tape” solution. This is a fully engineered, industrial-grade splice that maintains the grounding and integrity of your self-regulating cable.
Product Highlights:
-
Universal Compatibility: Specifically designed for Drexan MultiTrace® and other pro-grade self-regulating heat cables.
-
Weather-Tight Security: Each kit includes heavy-duty heat-shrink tubing and adhesive sealants to ensure a 100% waterproof connection that survives sub-zero winters.
-
Permanent Bond: Unlike mechanical connectors that can vibrate loose over time, this splice creates a permanent, fused connection.
Expert Tip from Eric Wimmer: “When you’re planning your layout, look for the ‘diverge’ points. Using a T-connection at the top of a valley allows you to feed both sides of a dormer simultaneously, saving you feet of cable and hours of labor.”
Important Installation Notes:
-
End Seals Required: Every “T” you create adds a new end to the system. Make sure you have an End Seal Kit for every new termination point.
-
Calculate Your Length: Ensure the total combined length of all three “legs” of the T does not exceed the maximum circuit length for your specific breaker size (refer to the Drexan Spec Sheet).
Common “T” Placement Scenarios:
-
The “Dormer Split”: If you have a dormer in the middle of a roof slope, run your main line up to the base of the dormer, use the T-Kit, and send one line around the left side and the other around the right.
-
The “Valley-to-Gutter” Diverge: When a major valley meets a long gutter run, place the T-Kit at the intersection. This allows the cable to track up the valley while simultaneously continuing the loop through the gutter.
-
The “Double Downspout” Feed: If you have two downspouts close together, use a T-connection to split the cable so both downspouts are protected without having to double-back the cable in the gutter.
Frequently Bought Together
Don’t get stuck mid-install—make sure you have the tools and terminations to finish the job.
-
[Drexan End Seal Kits]: Every time you “T-off,” you create a new cable end. You must have a professional end seal for every termination point to prevent short circuits.
-
[Professional Crimping Tool]: Ensure a “contractor-grade” connection. A secure crimp is the difference between a system that lasts 20 years and one that fails in the first storm.
-
[Extra Drexan MultiTrace® Cable]: Don’t come up short. Grab an extra 10ft or 20ft to account for the loops and valleys created by your new T-junction.
WHAT’S INCLUDED
- Drexan MultiTrace® Self-Regulating Cable (The gold standard for longevity)
- Factory-Terminated Power Plug (Grounded & Lighted) OR
- GFEP Factory-Terminated Power Plug (Grounded & Not lighted)
OTHER MATERIALS NEEDED:
- Aluminum Roof Clips: These corrosion-resistant clips are designed to hold the cable firmly in the “zig-zag” pattern on both asphalt shingles and metal roofs. Click Here
- M-1 Structural Adhesive: This is the only glue we trust. Unlike silicone that peels off in a year, M-1 creates a permanent chemical bond (up to 400 PSI) that cures even in damp or cold conditions. Requires a caulk gun. Click Here
How many Clips & Glue do I need? For a standard zig-zag or valley installation, a good starting point is to estimate 1 clip for every 24 inches (2 feet) of run.
- Note: This is an approximation based on typical roof layouts. Every project is unique, so don’t stress about getting the number perfect—you can always purchase extra clips or tubes of M-1 adhesive later if you find you need tighter spacing.
WHY CHOOSE A Heatcable.com ‘N’ PLAY KIT?
- Skip the Electrician: No hard-wiring required. These kits come with a pre-terminated, grounded power plug. Just mount the cable and plug it in.
- Instant Visual Check: The integrated Lighted Plug gives you instant peace of mind. One look tells you the system is powered up and melting snow. (Note: Actual plug brightness and color may vary).
VOLTAGE MISMATCH
WHY 120V MATTERS. DO NOT PLUG THIS 120V KIT INTO A 240V POWER SOURCE. HERE IS WHAT HAPPENS IF YOU DO:
The “Fixed Resistance” Danger: Old-school cables have a fixed resistance. If you double the voltage (by plugging into 240V), they get hotter and hotter until they burn themselves out or start a fire.
The Drexan Difference (Fail-Safe): Our self-regulating cable is smarter. If you hit it with 240V, it tries to generate 4x the power. However, because it is self-regulating, it senses that massive heat spike and fights to regulate it downward.
The Result: The cable wins the safety battle, but loses the war. The internal core is pushed beyond its limit trying to keep you safe. Instead of catching fire, it will simply “fail cold”—meaning the core degrades and will permanently stop producing heat.
Bottom Line: Plugging this kit into 240V won’t burn down your house, but it will ruin your cable and void the manufacturer warranty.
⚠️ CRITICAL WARNING
- It is recommended not to cut this cable. If a qualified technician cuts or modifies the cable for any reason, the warranty from Heatcable.com is immediately void. In this instance, the responsibility of the warranty falls entirely on the qualified technician performing the work. If you have excess cable, instead of cutting it, we recommend doubling it back into the gutter or downspout to increase melting power in that area.
- Code Compliance: Installation must strictly adhere to all applicable state and local electrical codes. We recommend consulting with a licensed electrician or your local building authority to ensure full compliance.
⚠️ INSTALLATION WARNING
Must be installed by a Qualified Electrician. To maintain the UL 508A Certification and ensuring the GFEP functions correctly, all input and output wiring must adhere to local, state, and national electrical codes.
✅ COMPATIBILITY CHECKLIST
Before you buy, confirm this kit fits your home:
- Voltage: 120V standard outlet (Verify your power outlet is 120V, not 240V).
- Gutter Type: Safe for Aluminum, Steel, and Copper gutters/downspouts.
- Outlet Proximity: Measure the distance from your roof edge to the outlet. You cannot use an extension cord. Ensure the kit length + lead is sufficient to reach the power source directly.
❌ INCOMPATIBLE / DANGER
To prevent fire, shock, or system failure, AVOID the following:
- NO EXTENSION CORDS: Never plug this kit into an extension cord. The resistance can cause overheating and fire. It must be plugged directly into a wall receptacle or controller.
- NO BURIED CABLE: Do not install this cable inside walls, under shingles, or buried in building insulation. The cable can be installed under our Patented Thermal Cartridge System.
- NO COILING: While Drexan cable is self-regulating, do not leave the cable coiled up in a tight spool while powered on. Unspool the cable completely before plugging it in to test.
⛑️ Important Safety & Specs:
- GFEP Protection: Safety is non-negotiable. If you do not select a kit with a built-in GFEP plug, the device must be used with a Ground-Fault Equipment Protected (GFEP) circuit.
- System Compatibility: The GFEP can also be applied in a custom or standard controller box, provided the controller already includes a GFEP component.
- Factory-Built Confidence: We don’t outsource our quality. These are assembled right here in Utah by pros who know winter.
TOOLS & TIPS
- Caulk Gun: Required for applying the M-1 Structural Adhesive. (We recommend a high-ratio “dripless” gun for easier application in cold weather).
- Extension Ladder: To safely access your roofline.
- Clean Rags & Isopropyl Alcohol: Essential for cleaning smooth surface areas—such as membrane and metal roofs—where clips will be glued. Any dust or grime left on the surface will cause the adhesive to fail.
- Light Duty Brush: Essential for brushing away loose granules and debris on asphalt shingle roofs before installing clips.
- Measuring Tape: To ensure consistent spacing for your “zig-zag” pattern.
- Pliers: Helpful for crimping the roof clips slightly if needed for a tighter hold on the cable.
🔥 PRO-TIPS FROM THE FIELD
- Don’t just install it—install it like a pro.
- The “Hershey Kiss” Method: When using the M-1 glue, don’t smear it flat like paint. Apply a nickel-sized dollop (shaped like a Hershey Kiss) under the clip. Press the clip down until glue pushes through the holes, but leave a layer of adhesive between the clip and the roof. This creates a chemical bond that lasts for decades.
- Create the “Melt Channel”: Remember, the cable doesn’t melt the whole roof; it creates a path for water to escape. Ensure your cable extends past the roof edge (1 inches or more) over the gutter to prevent an ice dam from forming right at the lip.
- Check Your GFEP: If you aren’t buying the GFEP plug option, you must plug this into an outlet protected by a GFEP breaker. We recommend testing the breaker before every winter season. Note: Your GFEP may also be in your controller.
- The “Drip Loop”: When plugging the unit in, make sure there is a small loop in the power cord below the outlet. This prevents water from running down the cord and directly into your electrical socket.
