Pair of 27-Inch Quiet Garage Door Push-Down Bumpers

These 27-inch quiet push-down bumpers are designed for commercial sectional garage doors that require controlled spring pressure when the door reaches the fully open position. Installed near the rear of the horizontal tracks, the bumpers compress as the door opens and apply downward pressure to the door.

This pressure helps keep the lift cables properly tensioned while the door is open, reducing cable slack and helping prevent the cables from jumping or unwinding from the cable drums. The cushioned bumper design also provides a quieter, smoother stop compared with allowing the door or rollers to strike a rigid track stop.

How Push-Down Bumpers Work

When a sectional garage door reaches the open position, the bottom section may move beyond the point where the door’s weight keeps the lift cables fully tensioned. This can allow the cables to become loose, overlap, or come off the drums.

Push-down bumpers compress against the door or roller assembly as the door reaches the rear of the horizontal tracks. The compressed springs apply downward force, helping maintain tension on the lift cables and supporting more reliable closing operation.

Common Applications

These bumpers are commonly used on:

• Commercial sectional overhead doors
• Taller or heavier garage doors
• Doors with long horizontal track runs
• Doors that experience cable slack in the open position
• Installations where the door needs a cushioned rear stop
• Replacement of worn, bent, noisy, or damaged pusher springs

Package Contents

• Two 27-inch quiet push-down bumper assemblies

Mounting fasteners, track brackets, and other installation hardware are not included unless specifically shown or stated with the product.

Compatibility

Push-down bumpers must be selected according to the door’s size, weight, track configuration, available mounting space, opener type, and required compression force.

The 27-inch size is generally intended for commercial door applications and may provide excessive force for smaller residential doors or certain garage door openers. Compare the dimensions and operating requirements with the existing bumpers before ordering.

Installation and Safety

Both bumpers should be mounted evenly so they contact and compress at approximately the same point during the opening cycle. Incorrect positioning or excessive compression can place unnecessary strain on the garage door, tracks, rollers, or opener.

Garage doors contain springs, cables, and other components under high tension. Installation and adjustment should be performed by a trained garage door technician.
