Dormakaba 75343 – Frequently Asked Questions

1) What is this Dorma 75343 offset arm designed for?
This is a 3/4 offset standard and heavy duty steel bottom arm specifically designed for lead-lined doors up to 1 3/4 inches thick. The right-hand configuration works with right-swing doors.
2) How do I determine the correct door handing for this arm?
Stand on the pull side of the door. If hinges are on your right, you need a right-hand arm. This model is for right-hand doors only.
3) What door weights can this arm handle?
This heavy duty steel arm is designed for standard and heavy weight lead-lined doors. Verify specific weight capacity with door closer manufacturer specifications for your complete assembly.
4) Is the satin chrome finish suitable for commercial applications?
Yes, satin chrome provides durable corrosion resistance for commercial use. It complements most hardware finishes and maintains appearance under regular use.
5) What makes this arm suitable for lead-lined doors?
Lead-lined doors are significantly heavier than standard doors. This heavy duty steel construction provides the strength needed to properly control these specialized doors in medical and industrial facilities.
6) How does the 3/4 offset affect installation clearance?
The 3/4 inch offset provides clearance between the arm and door frame. This prevents interference during door operation and accommodates standard frame profiles.
7) What other components are needed for a complete closer assembly?
You'll need a compatible Dorma door closer body, top arm, and appropriate mounting hardware. Check with manufacturer templates for complete parts list for your specific closer model.
8) Can this arm be field-adjusted for different door weights?
The arm itself is fixed. Adjustments for door weight and speed are made at the closer body through adjustment valves. The arm must be properly sized for the door application.
9) What installation considerations apply to lead-lined doors?
Lead-lined doors require reinforced frame mounting and proper closer sizing. Follow manufacturer templates exactly. Consider wall reinforcement for the additional door weight and closing forces.
10) How do I verify compatibility with existing door closers?
Check your existing Dorma closer model number against manufacturer compatibility charts. Arm mounting points and pivot specifications must match exactly for proper operation.
11) What maintenance does this steel arm require?
Periodically check mounting hardware tightness. Clean with mild soap and water. Inspect for wear at pivot points. The steel construction provides long service life with minimal maintenance.
