HEAVY DUTY AND STURDY, WON'T MOVE AN INCH: Our heavy-duty truck topper clamps can withstand heavy pressure, they are especially useful if you have a shell with a larger fabric-covered bottom mount where it connects to the bed. 6 sets of camper clamps greatly increase the stability
EASY INSTALLATION, WON'T LEAVE A PERMANENT HOLE: You can quickly install them within minutes. Just put the camper clamps into the bed, then put the screw into the hole, and finally tighten the screw with a wrench. No drilling is required, perfect if you don't want to drill holes for a permanent install
NON-SLIP DESIGN, SNUGGED DOWN TIGHT: Our truck bed clamps have small nuts to prevent the screw from slipping when tightening. The texture on the clamps can increase the contact friction and provide a good grip
NOTE: Our suggestion is to let these camper cap clamps do their job and not OVERTIGHTEN to prevent bending. Please measure the relevant size before purchasing, and the maximum size applicable is 1.4 in(3.55 cm)
