RCI TJ10X28 Top Jamb Kit for 8310

Place compatible 8310 hardware at the upper door-frame location with an RCI top jamb kit. TJ10X28 is described as a Top Jamb Kit in the X 28 configuration for 8310. That relationship matters when the installation calls for a top-jamb hardware arrangement rather than a component intended for another position on the opening. Top-jamb mounting places related physical-security hardware at the head of the frame. Select this kit when the existing opening, mounting method, and 8310 hardware arrangement call for that location. The product is mounting hardware rather than the primary controlled device, serving as the supporting kit associated with the installed security assembly. Its application is tied to a door-frame position, making the mounting location a central consideration during replacement or new installation work. The X 28 designation is part of this kit's stated product description. Its connection to 8310 is the key compatibility reference for a replacement or new installation involving that hardware arrangement. Review the installation position, frame condition, and 8310 configuration before selecting a top-jamb kit. This approach helps ensure that the mounting hardware matches the intended position at the opening and the related physical-security equipment.
