Corbin Russwin 597F78 Standard Full Cover with Insert Assembly for Commercial Door Closers

Restore the clean, professional appearance of your commercial entries with the Corbin Russwin 597F78 Standard Full Cover and Insert Packet. As an authentic OEM replacement part from ASSA ABLOY, this high-impact cover package is engineered to fully enclose the closer body mechanism, protecting internal regulating valves from tampering, dust, and environmental wear.

Designed for heavy-duty institutional environments, the 597F78 is the standard factory cover shipped with all premium Corbin Russwin DC3000 and DC6000 Series Grade 1 surface door closers. It features a non-handed, symmetrical construction that adapts perfectly to regular, parallel arm, or top jamb mounting orientations. The included insert pocket packet enables a clean cosmetic seal around the pinion shaft, hiding ugly mechanical internals while maintaining quick access for routine speed adjustments.

Product Features

  • Genuine OEM Component: Authentic factory replacement part designed specifically by Corbin Russwin (ASSA ABLOY).

  • Universal Compatibility: Fits all standard Corbin Russwin DC3000 and DC6000 Series surface-mounted door closers.

  • Non-Handed Design: Reversible geometry seamlessly accommodates both Left Hand (LH) and Right Hand (RH) door configurations.

  • Tamper Resistant Profile: Completely encapsulates the cast iron closer body, shielding the captured control valves against unauthorized adjustments.

  • Premium Integrated Insert Packet: Includes the required structural pocket inserts to ensure a flush, seamless seal around the arm spindle assembly.

  • Architectural Powder Finishes: Available in a range of durable, rust-resistant painted finishes (including 689 Aluminum and 690 Dark Bronze) to align with existing facility hardware.

Corbin Russwin 597F78 689 – Frequently Asked Questions

1) What size is the Corbin Russwin 597F78 closer cover, and will it clear my door frame and stop?
It measures 11-5/8 inches (295 mm) long, 3 inches (76 mm) high, and 2-3/4 inches (70 mm) deep. Those are the numbers to check against your available space when the closer sits close to a header stop, a transom, or a parallel arm bracket on a narrow top rail. On parallel arm mounting the cover projects the 2-3/4 inch depth off the door face, which matters on openings with tight adjacent wall returns.
2) Do I need to order a left hand or right hand version of the 597F78 closer cover?
Neither. The 597F78 is non-handed and field reversible, with symmetrical geometry that works on both left hand and right hand doors. The same part also covers regular arm, parallel arm, and top jamb mounting orientations, so one cover handles all three installs.
3) I have a tenant adjusting the door closer speed. Will a full cover stop that?
That is the main reason to fit one. The 597F78 fully encloses the cast iron closer body and shields the control valves from unauthorized adjustment, along with dust and general environmental wear. On school corridors, multi-family common doors, and healthcare openings, that is usually the difference between a closer that stays where the tech set it and one that gets turned every month. It is a commercial-duty part, built for heavy-duty institutional use.
4) My old door closer cover is cracked and faded. Can I just replace the cover instead of the whole closer?
Yes, provided the closer body itself is a Corbin Russwin DC3000 or DC6000 Series unit and still working. The 597F78 cover and insert packet is sold as a standalone replacement, so a cracked, dented, or sun-faded cover does not force a full closer swap. That is the usual fix on a building where the closers are sound but the entries look tired.
5) Does the 597F78 come with the insert pieces, or do I have to order those separately?
The insert packet is included. The 597F78 ships as a cover plus the pocket inserts that seal around the arm spindle, so nothing extra is needed to close up the pinion shaft opening cleanly. You still keep access for routine closing and latch speed adjustments, since the cover comes off rather than being permanent.
6) What finishes does the Corbin Russwin 597F78 closer cover come in, and can I match the other closers in my building?
Six finishes: 600 primed for painting, 689 aluminum painted, 690 dark bronze painted, 691 light bronze painted, 693 black painted, and 696 satin bronze painted. Those are the standard Corbin Russwin closer finish numbers, so ordering the same number that is on the closers elsewhere in the building gives you a match. Pick 600 if the doors are painted to a custom color, since it arrives primed and ready for topcoat.
7) Is the 597F78 an OEM Corbin Russwin part or an aftermarket cover?
Genuine OEM, made by Corbin Russwin (an ASSA ABLOY brand) under part number 597F78. It is the same cover shipped from the factory with DC3000 and DC6000 Series closers, which is what matters when a spec or a facility standard calls for manufacturer parts rather than a generic replacement.
8) Will putting a plastic cover on my door closer affect the fire door or ANSI rating?
The 597F78 is made of high-impact molded plastic and meets ANSI/BHMA A156.4 requirements when paired with the closer body. It is a cosmetic and protective enclosure over the closer, not part of the operating mechanism, so it does not change how the closer controls the door. Keep in mind the rating belongs to the closer assembly as a whole, not the cover on its own.
