The AEC 07 is a commercial version of the VG95234 jam nut receptacle.
The VG95234 style reverse bayonet jam nut receptacle provides increased environmental protection due to its single mounting hole. It features a low-profile nut where it is “jammed” up against a standard nut to lock the two in place. An integrated silicone O-ring offers additional sealing while the integrated splash-proof backshell provides environmental protection and strain relief.
