Professional Installation Checklist

1. Record door width, weight, frame reveal, swing, handing, desired opening angle and top-rail reinforcement.
2. Confirm the exact arm package's mounting location, clearance, compatible closer accessories and any separately required plate or bracket.
3. Select and adjust Size 1–6 closer spring power for the actual door application; follow approved manufacturer adjustment instructions.
4. Set hydraulic sweep, latch, delayed action and advanced backcheck while monitoring the door's real opening and closing behavior.
5. Confirm the opening's accessibility and fire-door listing; mechanical hold-open arms are not automatically approved for fire-rated doors.
6. Test latch engagement, safe egress, backcheck and any stop/track hardware through repeated cycles.

Commercial Applications and Ordering Notes

Used on correctly prepared high-traffic commercial entrances at offices, retail facilities, schools, healthcare sites, warehouses and institutional buildings.

Verify installation plates, fasteners and shipping carton weight for the actual selected SKU.
