This product is intended for use in Automotive applications using a 2” x 4” steel tube frame. Rather than route your plumbing and wiring outside the frame use this flush fit weld-in CNC machined 1018 steel plate and custom water jet cut 6061 aluminum plate to cleanly route through the frame rail itself!  The aluminum plate mounts to the steel cutout using three stainless steel fasteners (included).  The plate is pre-cut for a size 20 Amphenol 97 Series connector and comes with an empty hub and 4 stainless steel mounting screws (inserts are purchased separately and are dependent on your application). There are two precut  1/8” holes for plumbing fittings which can be used for a variety of needs depending on your application. They have been tested up to dual AN 6 fittings while still fitting in the frame rail and making a 90 degree turn (see photos). Custom plate configurations and other rail sizes can be designed on an as needed basis – please inquire for pricing. To complete your transaction go into your "Cart" on the top right of the page.
