Compatibility and Selection
Match the 4L280 designation to your existing belt or the operator manufacturer’s parts list. The 28-inch measurement refers to the belt’s outside circumference, not its inside length or the distance between pulleys.
Confirm the required belt profile and operating requirements before ordering. Correct width and length alone do not establish compatibility.
Installation Notes
Inspect the pulleys for wear and alignment before installing the replacement belt. Set tension according to the operator manual: excessive tension can overload bearings, while insufficient tension can cause slipping.
Release tension before fitting the belt; do not pry or force it over a pulley rim. Keep the belt and pulley grooves free of oil and grease.
Safety Warnings
Disconnect and lock out operator power before removing guards or servicing the drive. Keep hands, clothing, and tools clear of belts and pulleys. Reinstall all guards before restoring power, then test door operation and safety devices according to the manufacturer’s instructions.
Professional installation is recommended. Repair any binding or imbalance in the door before operating it.
