Installation Instructions YH-94 Subpanel Hinge Kit The kit includes (4) subpanel mounts, (4) set screws, (1) allen wrench, (1) static hinge, (1) spring-loaded hinge, and (4) rivets. The YX-93 Kit is designed to support the installation of subpanels, hinge panels, or dead-fronts that require the ability to open or swing. To install the subpanel mounts, slide the mount into the track found in the corners of the enclosure base. Insert the Set Screw into the middle channel using the wrench provided, and screw it in until it is flush with the mount. This ensures full engagement. An alternative method is to install the Set Screw through the hole on the bottom of the mount into the channel. Attach the hinges to the subpanel. Then, slide the hinges into place on the mounts as shown. The panel can be fastened to the mounts with a #10-32 screw.
