Don-Jo SH94545 Spring Hinge | 4-1/2" x 4-1/2" | 630 Satin Stainless (US32D)
The Don-Jo SH94545 is a spring hinge sized 4-1/2" x 4-1/2" and finished in 630 satin stainless (US32D). Designed for doors that must return to a closed position automatically, this self-closing butt hinge is ideal for corridors, stairwells, and other code-required self-closing door applications. Its UL Listed rating makes it a dependable choice wherever fire-rated assemblies demand a compliant, automatic-closing hardware solution.
Self-Closing Action for Code-Compliant Doors
The SH94545 delivers reliable self-closing door performance through an integrated spring mechanism engineered to return doors consistently after each use.
- Integrated spring mechanism: Provides automatic door closing without the need for a separate overhead closer, simplifying hardware schedules on light-duty self-closing door openings.
- Adjustable spring tension: Allows installers to fine-tune closing force to match door weight and opening frequency, supporting ADA-compliant closing speed requirements on applicable openings.
UL Listed for Fire-Rated Door Assemblies
The UL Listed designation confirms the SH94545 meets the requirements for use on fire-rated door assemblies where self-closing hardware is mandated.
- UL Listed rating: Qualifies the hinge for fire door hardware schedules, satisfying inspectors and AHJ requirements on rated openings that call for automatic-closing hinges.
- ANSI K51071F compliance: Conforms to the ANSI/BHMA spring hinge standard, providing a recognized benchmark for performance and durability on commercial door projects.
Self-Lubricating Bearings and Satin Stainless Finish
The SH94545 features self-lubricating bearings and a corrosion-resistant 630 satin stainless (US32D) finish suited to high-traffic and moisture-prone environments.
- Self-lubricating bearings: Reduce maintenance intervals and support smooth, quiet operation over the life of the opening — an asset on high-cycle doors in institutional and commercial settings.
- 630 satin stainless (US32D) finish: Delivers corrosion resistance appropriate for exterior vestibules, healthcare corridors, and coastal or high-humidity environments where stainless hardware is specified.
- Non-handed design: The SH94545 installs on either hand of door without modification, streamlining procurement and jobsite inventory.
