The TAPCO P1050 is a cartridge single-lock fitting designed for use in panel and distribution board applications where secure, tool-assisted locking is required. Built to a 38mm cartridge format with a 63mm square footprint, this 2-pole component provides a reliable mechanical lock point for electrical enclosures and similar assemblies. It is typically installed by licensed electricians during panel construction, retrofit work, or maintenance procedures where cartridge-style locking hardware is specified.
The P1050 suits commercial and industrial electrical installations where standardized cartridge dimensions are required. The 38mm cartridge sizing and 63mm square mounting profile make it compatible with panel configurations that call for a 2-pole single-lock arrangement. It is appropriate for new construction panel builds as well as service and upgrade work on existing distribution equipment.
Designed as an OEM-style replacement or direct-fit component for electrical panels and distribution boards specifying a 38mm cartridge single-lock 2-pole 63mm square mounting format.
Installation should be performed by a qualified electrician in accordance with applicable NEC requirements. De-energize and lock out the panel before beginning any cartridge fitting work. Verify that the mounting cutout and panel depth are compatible with the 63mm square footprint and 38mm cartridge depth before final installation.
