All-Vac
The All VAC 3-inch concave vacuum cup with metal mount provides a reliable, temporary mounting solution without drilling holes. Featuring a 15 lb load capacity and a 1/4-20 threaded stud (5/8" length), this vacuum cup is ideal for mounting cameras, surveying equipment, and handling light materials. The 3-inch (76mm) diameter concave rubber pad creates a strong seal on both flat and curved surfaces.
