Description
MAXUM JHDC is a next-generation DC jackshaft with a built-in hoist. It mounts on the wall beside the door for high- or vertical-lift sectionals and rolling doors.
Pick this when…
- You need a hoist (floor-level hand chain) — not JDC (no hoist) and not RJDC (release only).
- You need a jackshaft (side-mount) — not a ceiling trolley (that is TDC).
- Sectional or rolling steel doors up to 2200 lb (comparison chart).
