Our new Strap Holder with Stainless Steel D-ring with TreeFrog 15cm vacuum cup, with more than 100kg holding capacity is a perfect temporary mounting solution. The D-ring moves around freely on the vacuum cup, to the angle you wish to have and the D shape ring keeps the strap in the center position to hang or hold anything to it to your project. It could be attached to any rigid smooth surface and easily removed when you do not need it. You can also attach a flex arm or other screw directly into the 6mm metric threaded copper inserts.
