Rubber Bed Mat Gooseneck Holes

[JW2024]

I finally have a need for my gooseneck ball and safety chain anchors. I have the GM bed mat. I didn’t want to roll the mat up to use the holes so I drilled some in the mat. I 3D printed some drill guides and drilled pilot holes up from under the bed. Then removed the mat and drilled 3.25” holes. Worked great.

I have the 3/8 thick GM mat. I used a hole saw to make holes for my camper anchor eye-boots. It made nice clean holes.
