The Meltric 514P0N15 poly handle is intended for use with the DSN100 series male inlets as part of a complete assembly. It features a 1-1/2" NPT threaded opening which accommodates 1.26 - 1.56" cable. When connected to a male inlet, it has advantages such as a durable construction, a lightweight design, and water tight operation. For washdown applications, the poly (PH) handle works better when compared to non-threaded handles, because of its threaded opening. This is assuming that the handle is also connected to a properly sealed cable gland. Overall dimensions: 3.58" Diameter x 4.41" Height. Interior Volume: 25 cubic in. Ground shipping only
