Clopay Cable & Drum Replacement: The Hayward Owner’s Guide
Clopay cable and drum replacement in Hayward typically runs $130-$250 installed, and we stock the common Clopay drum sizes and 1/8-inch and 5/32-inch aircraft-grade cable on every truck. Most replacements are completed in under 90 minutes once we confirm your model series. You’ll usually discover this failure when the door hangs crooked, one side lifts faster than the other, or the cable has unspooled from the drum entirely, often after a loud snap from the garage.
Which Clopay Models This Applies To
Clopay uses two primary drum systems across their residential line: standard-lift drums for headroom clearances of 10-12 inches, and low-headroom drums for tighter spaces common in Hayward’s older ranch and split-level stock. The part you need depends on your track configuration, not just the door width.
Check the sticker on the interior panel edge or the end of the torsion tube for your model series. Classic Collection and Gallery Collection doors from 2012-2020 often shipped with the 400-8 standard drum; newer Coachman and Grand Harbor lines may use the 400-12 or 400-54 low-headroom variant. The drum’s casting number is stamped on the hub face, visible once the cable is slack.
We carry Clopay-compatible OEM-spec drums and cables from DDM Garage Doors and Prime-Line, which match the original metallurgy and groove pitch. Aftermarket equivalents save roughly $30-$50 on parts without sacrificing cycle rating. For Clopay’s stamped-steel 8-foot and 16-foot sectional doors, mixing drum brands with different groove angles causes premature cable wear. We verify compatibility against your existing hardware before quoting.
Signs Your Clopay Cable & Drum Replacement Is Failing

- The door sits crooked when closed. One cable has stretched or slipped on its drum, creating unequal tension across the torsion tube. The lower corner on the loose side often gaps away from the weatherstripping first.
- A loud snap or pop, then silence. Clopay cables in Hayward’s coastal-influenced climate corrode from the inside out where moisture collects inside the cable loops. The snap is usually a strand-by-strand failure that releases suddenly under load.
- The cable is frayed or birdcaged near the bottom bracket. This is the highest-stress point in the cable run. On Clopay doors with factory-original hardware, we see this at 8-12 years in Hayward, sooner if the door is oversized or the springs are imbalanced.
- The drum spins but the door doesn’t lift. The cable has jumped its groove, usually because the drum is worn or the set screws have backed out. Continuing to operate the opener strips the drum grooves and turns a $200 repair into a drum-and-cable replacement.
- The door slams shut or free-falls when disengaged. A broken cable on one side removes all opposing tension. The remaining cable and spring now pull unopposed, which overtorques the good side and risks secondary failure.

| Service | Price Range |
|---|---|
| Single cable replacement (one side) | $130-$190 |
| Dual cable replacement (both sides) | $180-$250 |
| Cable + drum replacement (one side) | $160-$250 |
| Full cable, drum, and bearing plate service | $220-$340 |
Our Hayward pricing includes the part, labor, tension rebalancing, and a full cycle test before we leave. What moves you up or down within the range: drum material (cast iron vs. stamped steel), whether the bearing plate needs replacement, and if the torsion spring requires retensioning after the cable failure.
Clause 1 of The Haven Standard means you get the flat, written price before we touch a tool. Clause 4 means we photograph the failed drum and cable, show you the groove wear or corrosion pattern, and only then confirm the scope. The 365-Day Done Right Promise covers the installation and parts. No coupon needed.
DIY or Call Us?

There’s a safe middle ground here, and a hard stop.
What you can check safely: Visually inspect the cable for fraying with the door fully closed and the opener disengaged. Look for the drum casting number with a flashlight. Confirm whether the door is level when closed. These observations help us diagnose by phone and arrive with the right parts.
What you should not attempt: Unwinding a torsion spring to release cable tension, adjusting drum set screws while the spring is loaded, or reinstalling a cable onto a drum without proper winding bars. The stored energy in a standard residential torsion spring can cause serious injury. We’ve responded to Hayward calls where a homeowner’s socket wrench slipped off a set screw and the winding cone spun freely. The repair then included a wall dent and an ER visit.
We carry Clopay-compatible drums and cables on every truck, and Marcus Deller still sketches cable drum alignments by hand in a field notebook before complex installs. Name the part. Quote the range. Then fix it. Call (510) 330-2488 for a free estimate.
FAQs
Expect 10-15 years for cables and 15-20 years for drums in Hayward’s climate, though coastal moisture and temperature swings near the bay shorten that by 20-30% compared to inland California. Rust inside the cable loops is the hidden killer; the exterior can look fine while the core strands fail. Call (510) 330-2488 if you’re past the 10-year mark and noticing any symptoms.
No. A frayed or broken garage door cable is always replaced, never spliced or re-swaged. The safety margin is too thin and the liability too high. We replace the matching cable on both sides simultaneously to maintain balanced tension. Call (510) 330-2488 for an exact quote - estimates are free.
Most replacements take 60-90 minutes from truck arrival to cycle testing, assuming the torsion spring is intact and the bearing plate hasn’t been damaged. If the cable failure caused the door to drop off-track, add 30-45 minutes for realignment. We stock the common Clopay drum sizes and cable gauges on every truck, so there’s no parts run.
Yes. We carry 1/8-inch and 5/32-inch 7×19 aircraft-grade cable, standard-lift and low-headroom drums in 8-inch and 12-inch diameters, and the full range of Clopay-compatible bottom brackets and cable sleeves. For discontinued Clopay hardware, we source exact-match aftermarket equivalents with identical metallurgy and cycle ratings. Call (510) 330-2488 to confirm your model and we’ll verify stock before dispatching.
