The D1100-216 18' Vertical Lift Garage Door Cable Drums are designed for vertical-lift overhead door systems where the door travels straight up instead of using a standard-lift or high-lift track setup. These drums are commonly used on commercial overhead doors, industrial sectional doors, warehouse doors, loading dock doors, and other applications requiring vertical lift cable travel.

This drum set is rated for doors up to 18' high and has a 660 lb capacity per drum. The D1100-216 drums are designed for use with cable up to 3/16" diameter and are commonly sold as a left-hand and right-hand pair. They are used as part of a properly matched counterbalance system with torsion springs, cables, shaft, bearings, bottom fixtures, and vertical-lift track hardware.

Vertical-lift cable drums are not interchangeable with standard-lift drums. The drum must match the door height, lift type, shaft size, cable size, and door weight requirements. Using the wrong drum can cause poor cable tracking, unsafe door balance, cable failure, or serious damage to the door system.

Compatibility & Fitment

The D1100-216 vertical lift drum is intended for compatible vertical-lift garage door systems with a maximum door height of 18'. It is commonly associated with a 660 lb capacity per drum and a maximum cable size of 3/16".

Before ordering, confirm the door lift type, door height, door weight, shaft size, bore size, cable diameter, cable length requirement, spring setup, and whether the door requires a matched left-hand and right-hand drum pair.

Common cross references for this drum include Apco 1100-18, DNS 236-18, OMI 18 VL, and M280-5500. Always verify the drum number and specifications before replacing existing drums.

Installation Notes

Install these drums only on compatible vertical-lift door systems. Confirm the correct left-hand and right-hand drum placement before installation. Cable length is commonly calculated using the vertical-lift cable formula: floor to shaft center plus 237" minus the door height, but the final cable length should always be verified against the actual door, shaft location, drums, and manufacturer requirements.

The drums must be secured properly to the torsion shaft, and the lift cables must seat correctly in the grooves without crossing, jumping, or rubbing. After installation, the door must be balanced and tested through several full cycles.

Safety Notice

Garage door cable drums work with torsion springs, shafts, cables, and bottom fixtures under high tension. Incorrect drum selection or installation can cause serious injury, death, door damage, cable failure, or unsafe operation.

This product is intended for professional garage door and commercial overhead door use. Installation should be performed only by trained technicians using proper tools, correct cable assemblies, matched spring components, and safe procedures. Never operate a door with loose cables, incorrect drums, damaged bottom fixtures, or an improperly balanced spring system.
