Sealing is achieved with a tongue and groove construction and a one-piece UL listed silicone gasket.
All versions have a RAL7035 grey base. The polycarbonate range is available with a plain or styled opaque lid, a clear lid or a smoked lid; the ABS units have a plain or styled opaque grey lid. The lid is secured with self-captivated M4 stainless steel machine screws, located outside the sealed area and threaded into integral stainless-steel bushings to preserve the sealing integrity after repetitive assembly and disassembly.
The internal features vary with size. M3 threaded brass inserts and/or standoffs for PCB or inner panel mounting and vertical PCB guides are provided in all but the smallest B size. DIN rail mounting tabs are moulded into most sizes.
The polycarbonate versions are UV stabilised for outdoor use. The grey material has a UL94-5VA flammability rating, the clear and smoked lids are rated UL94V-0. The ABS versions are rated UL94-HB.
