Hammond HLP4UR 4U Round-Hole Pivoting Rack Rail Kit

The HLP4UR is a 4U round hole pivoting rail kit that lets standard 19-inch EIA-310 rack equipment be mounted inside Hammond HLP, HLPB and ERP enclosure systems. It suits IT and AV integrators, control panel builders and OEM engineers who need switches, patch panels, industrial PCs, PLCs or communications hardware installed in an industrial enclosure rather than an open rack.

The kit is built around two assemblies plus fasteners: one HLP rotating bracket, one HLP rotating rail and two thumb screws. Because the rail pivots, mounted equipment can be swung out for wiring and servicing while the enclosure keeps a compact footprint. Mounting thumb screws are included, so no separate hardware order is needed to attach the rail assembly.

HLP4UR is made from mild steel and, per the drawing, is finished in painted black textured. The HLPUR Series rails are manufactured from heavy-duty 14-gauge steel and carry precision 1U rack unit markings that simplify equipment installation and future expansion. This part uses round-hole EIA rail mounting.

Key dimensions from the part drawing are a 7.00 in (178 mm) 4U mounting height, 7.50 in (190 mm) front-view width and an 8.25 in (210 mm) overall depth reference, with the series specifying a 19.00 in EIA mounting width. Shipping weight is 4 lbs (1.81 kg).

HLP4UR is made in Canada, is USMCA compliant, TAA-compliant, RoHS compliant and REACH compliant, with ECCN EAR99 and tariff code 8538.10.0000. The HLPUR Series is manufactured in North America in an ISO 9001 certified facility.
