This aluminum end cap is for use with Watertight Enclosure for ROC/AUV (8'' Series). We designed these end caps to have a greater depth rating than the clear acrylic end caps. Depth rating to be determined.
Aluminum is much easier to machine than acrylic. If you’d like to drill your own holes, tap holes, etc., then this end cap is the way to go.
If you’re looking for a complete set of parts for an enclosure, we highly recommend using the enclosure configurator here.
