Trailer tarpaulin support bar clamps (Gaupen) - strong

The support bars of the Gaupen trailer (Norwegian) slides on top of the sides of the trailer. This is somewhat irritating when adding/removing the tarpaulin cover. These clamps fixes this problem by securing the support bars.

Print on the side. Should not need supports (some bridging required).

Two types of screw included. The screw made to be printed on the side will get stronger than the upright version.
