Pick this when…
- You need a jackshaft with a floor-level chain hoist — not a ceiling trolley (TDC) and not a no-hoist jackshaft (JDC).
- Manual move is the hoist chain (green / red ropes) — not a sash-chain release (RJDC).
- Sectional and rolling steel up to 2200 lb (comparison chart).
- Battery backup is a kit (DC7AH) — not in the carton.
