Pemko CFM83SLI-HD1 Full-Mortise Heavy Duty Short Leaf Inset Hinge
The Pemko CFM83SLI-HD1 is a high-performance Full Mortise Continuous Geared Hinge specifically engineered for new door applications. This Heavy Duty model features a Short Leaf Inset (SLI) design, making it the premier choice for hollow metal frames where the inset must conform to strict S.D.I. (Steel Door Institute) specifications. By distributing the door's weight uniformly along the entire length of the frame, this hinge eliminates sagging and ensures perfect long-term alignment for doors up to 540 lbs.
High-Performance & Alignment Features
- SDI Specification Compliance: Specifically designed for use with hollow metal frames to ensure the inset perfectly aligns the door and frame according to industry standards.
- Heavy Duty Load Bearing: The HD1 rating supports high-traffic commercial doors weighing up to 540 lbs, making it ideal for lead-lined healthcare doors and oversized entries.
- Short Leaf Versatility: Accommodates a wide range of door thicknesses from 1-3/4" to 2-1/4", providing a precise fit for standard and extra-thick commercial doors.
- Smooth ADA Operation: Precision-engineered gears allow for an operating force of 1/2 lb or less, ensuring effortless access and full compliance with accessibility standards.

Pro-Tip for Architects & Contractors
The Pemko CFM83SLI-HD1 is the "gold standard" for new construction projects where precision is non-negotiable. Because the gear mechanism provides 50% more bearing surface than traditional hinges, it significantly reduces maintenance costs over the building's lifecycle. For high-security or healthcare environments, this hinge can be customized with Hospital Tips (HT) or Fire Pins for 3-hour fire-rated assemblies. The included thread-forming screws allow for a rapid install into metal frames without the hassle of manual tapping.
