The Meltric 512P0N10 poly handle is made for use with the DSN30 series male inlets as part of a complete assembly. It has a 1" NPT threaded opening which accommodates .66 - 1" cable. When connected to a male inlet, it features such benefits as a durable construction, a lightweight design, and water tight operation. Due to its threaded opening, the poly (PH) handle works better for washdown applications when compared to non-threaded handles, provided it is attached to a properly sealed cable gland. Dimensions: 2.63" Diameter x 3.15" Height. Ground shipping only
