A simple way to secure knock-down panel constructions, these button-and-socket couplers are literally a snap to engage and disengage. Mounted to one panel, the 18mm (3/4") diameter button projects 8mm (5/16") and connects with a socket fitting on an adjacent panel, locking with an audible click, so you can be sure all parts are properly joined.
The in-line version requires a 52mm × 45mm (2 1/8" × 1 7/8") mounting area for the socket and can be surface-mounted directly to the panel face using #8 pan-head screws, creating an 8mm (5/16") offset between the panels, or can be recessed (#8 flat-head screws required) for a closer fit, with 3mm (1/8") of offset*.
To join two perpendicular panels, the 90° coupler holds the edge of one panel flush against the other panel face. The 90° socket requires a 50mm × 18mm (2" × 1 1/16") mounting area and uses #8 screws.
Both the in-line and 90° couplers are available with two different types of button fixtures; one has a 7/32" diameter hole for a #10 wood screw and the other has a 6mm hole for use with a 5mm diameter Euro screw.
All parts are tough nylon; mounting screws not included. Four buttons and four sockets per set.
