The GIBRALTAR SL-804 is a side lock component designed for use in mold blank and punch die set assemblies. It serves as a mechanical locking element that secures mold components in position during die casting and injection molding operations. The SL-804 features a 1/4-20 thread size and measures 2.75 inches in height, 3 inches in width, and 0.75 inches in length. At 0.5 pounds, it is a compact, single-piece hardware unit. Installation is typically performed by toolmakers, mold makers, or precision machining professionals working with production tooling setups.
The SL-804 is suited for die cast mold and injection mold applications where consistent, repeatable side locking is required. This part is sold individually and is appropriate for both new tooling builds and replacement of worn or damaged side lock hardware in existing mold assemblies. It is commonly found in production environments requiring precise mold alignment and secure component retention across repeated cycles.
Designed for use with die cast mold and injection mold assemblies requiring a 1/4-20 threaded side lock component.
Installation of mold side locks should be performed by qualified toolmakers or mold technicians familiar with precision die set hardware. Ensure all mold components are fully de-energized and press equipment is locked out before servicing. Use calibrated torque tools appropriate for 1/4-20 fasteners and verify proper seating and alignment before returning the mold to production. Follow applicable shop safety procedures and equipment manufacturer guidelines during assembly.
