Clopay Cable & Drum Replacement Nationwide

Clopay Cable & Drum Replacement: The North Hollywood Owner’s Guide

We stock and install Clopay-compatible cable and drum assemblies for most residential models, with typical installed pricing in North Hollywood running $130-$250 depending on door height and whether both sides need replacement. Most calls we take are completed same day because the parts travel on our trucks. You’ll usually notice the problem when the door hangs crooked, one side lifts faster than the other, or you hear a metallic thump from the header as the cable slips its drum groove.

Which Clopay Models This Applies To

Clopay has used several drum designs across their product lines, and matching the right one matters more than most homeowners expect. The stamped part number on your existing drum, usually found on the inner face near the hub, is the fastest way to identify it. If that label is worn off, we measure the drum circumference at the cable groove and count the number of cable wraps it accepts at full lift.

Classic Collection and Gallery Series doors from roughly 2008 forward typically use a 4-inch diameter high-lift drum with a 12-ball cable anchor pattern. Older Reserve Wood and Coachman units sometimes shipped with a 3 3/4-inch drum and a different anchor spacing, which means an aftermarket drum that fits one will not seat properly on the other. We carry both OEM Clopay drums and equivalent-grade aftermarket units from DDM and National, and we’ll show you the difference before we install. The aftermarket drums we use meet the same tensile and hardness specs; the OEM carries the Clopay logo and a longer markup. For most North Hollywood homes, the aftermarket equivalent is the square deal. We are an independent service provider with no affiliation to Clopay Corporation.

Signs Your Clopay Cable & Drum Replacement Is Failing

• Door hangs crooked or one side drags. When a cable frays or a drum develops a worn groove, the lift becomes uneven. The side with good cable tension rises while the lagging side strains the opener or the remaining cable.
• Metallic grinding or popping from the header area. A cable that has slipped its drum groove will ride against the drum flange instead of seating in the groove, producing a rhythmic pop each cycle. This damages both parts quickly.
• Cable visible off the drum or wrapped incorrectly. If you can see cable bunched at one end of the drum or hanging slack, the set screws have loosened or the drum hub has cracked. Operating the door in this condition risks full cable detachment.
• Door feels heavier than usual to lift manually. A failing drum may not provide the mechanical advantage designed into the lift geometry. The spring still carries weight, but the door fights you because the cable is not transferring force efficiently.
• Rust dust or broken wire strands near the bottom bracket. Clopay cables run through a pulley or bottom bracket that traps moisture, especially in North Hollywood where morning marine layer keeps concrete damp half the year. Surface rust graduates to internal strand failure.

Replacement Cost & What’s Included

The range depends on door height (8-foot cables cost less than 10-foot), whether the bottom bracket also needs replacement, and if the torsion spring requires rebalancing after we correct the lift geometry. We state the flat price before touching a tool. Parts, labor, lubrication, and a safety check of the full system are included. Every cable and drum job carries our 90-Day Done Right Promise in writing. If the door does not cycle quietly and evenly, we return at no charge.

DIY or Call Us?

There is a safe middle ground here, and then there is a hard stop. You can inspect the cable for fraying and confirm whether it has slipped its groove without risk. You can also verify the door is closed and the opener disconnected before you look.

What you should not do is loosen the set screws on a torsion spring shaft to remove or reposition a drum. The spring stores enough torque to cause serious injury if the winding bars slip or the shaft turns unexpectedly. Cable replacement on a torsion system requires releasing spring tension, a procedure that demands proper tools and training. Extension spring setups carry their own risks when cables are under load. We have handled calls in North Hollywood where a well-meaning owner turned a $180 cable job into a door-off-track repair with bent section damage. The door should open. Let’s make that happen. Call (747) 239-5578 and we will quote the work before we start.
