The Simpson HSKP5.75X14.5KT is a high-capacity, concealed beam hanger kit engineered for mass timber construction. With code-listed load ratings up to 32 kips and a fire-resistance rating of two hours, this solution delivers superior structural performance while preserving the clean, exposed-wood look builders and architects demand.

This all-in-one kit includes a heavy seated knife plate and Strong-Drive SDCF Timber-CF structural screws for easy and secure installation. Designed for beam-to-column connections, splicing, or wood-to-steel applications, it’s a go-to solution for glulam, CLT, and other engineered wood assemblies.

Kit Includes:

• (1) HSKP5.75X14.5 Heavy Seated Knife Plate – precision-welded steel for strength and durability
• (1) CJTPL 1/2" Dia. Steel Dowel
• (16) SDCF27614 0.390" x 6-1/4" Strong-Drive SDCF Timber-CF Screws
• (6) SDCF22858 0.315" x 8-5/8" Strong-Drive SDCF Timber-CF Screw

Key Features:

• High Load Capacity: Rated up to 32 kips for demanding mass timber projects
• Concealed Aesthetic: Keeps all hardware hidden for a clean architectural finish
• Fire-Rated: Meets two-hour fire resistance for code compliance
• Angled Fastener Installation: Patented tab design allows for 45° screw angle, increasing stiffness and load rating
• Factory-Ready: Designed for offsite fabrication and fast, reliable on-site installation

Applications:

• Concealed beam-to-column connections in exposed timber frames
• Beam splicing and inline joins in engineered wood structures
• Wood-to-steel beam or column interfaces in hybrid builds

Installation:

1. Position the HSKP knife plate at the beam seat location on the supporting structure
2. Secure the hanger using the provided SDCF Timber-CF screws at the designated 45° angle
3. Lower the beam into place – generous fit-up tolerance allows for fast and accurate alignment
4. Final-torque all screws to manufacturer specifications

NOTE: The correct fasteners installed in the correct position must be used to achieve published load values
