With the sealed front mounting versions, countersunk sealing screws, together with the sealed back side of the gripping tray, prevents the entry of fluids or dust into the housing interior where the tray is being mounted to.
The GN 7330 gripping trays are made of die-cast zinc and supplied with a powder coating in either black or silver. Coating in a different color is available upon request.
The GN 7332 stainless steel gripping trays are made of high-quality deep-drawn, rust-free stainless steel with the surface blasted to a fine matte finish.
On each of the versions, the threaded studs used to mount the tray from the back are not visible from the front.
