Dorma NFHD Narrow Frame Bracket (DS / SPA)
The Dorma NFHD is the narrow-frame heavy-duty bracket for DS and SPA arms. Price List 38 lists it at $45. The glossary and 8600 brochure (printed p.29) call it out when total frame depth is under 4-1/2 in.
It replaces the standard spacer block that ships with the arm. The 7400 note says NFHD mirrors the 8600 part.
When is NFHD required instead of the arm spacer block?
When total frame depth is under 4-1/2 in. The 8600 brochure: NFHD is used in lieu of the spacer block supplied with the arm.
Is NFHD the same as FTHD?
No. NFHD is the narrow-frame HD bracket. FTHD is the flush-transom HD bracket. Both are DS/SPA accessories.
Institutional Grade Features and Benefits
- DS / SPA only: not the standard P86 soffit family.
- Frame depth under 4-1/2 in: glossary / brochure trigger.
- Replaces the arm spacer block: brochure -- in lieu of the block supplied with the arm.
- Finish on this listing: painted 689 / 693 / 695.
- This listing: does not include the closer body, arm, or cover.
Applications
DS door-saver or SPA super-parallel openings where the frame is too shallow (under 4-1/2 in) for the standard spacer block.

Technical Specifications
Facts below are from the Dorma glossary (plates_brackets, cover_codes, mounting_templates, sizes.min_door_rail) and Price List 38 accessories. This plate is not the closer. UL/cUL, ANSI/BHMA A156.4 Grade 1, and the 25-year closer warranty apply to the 7400/8600 closer body, not to the plate.
