4-1/2″ Concave Vacuum Cup with 1/4-20 Thread x 1/4″ Stud
The All VAC LJ45AM1420T14L is a 4-1/2 inch (11cm) diameter concave rubber vacuum suction cup with a 40 lb (18kg) load capacity. This professional-grade vacuum mount features a black aluminum mount with 1/4-20 thread and 1/4" length stud for secure equipment attachment. The concave design makes it particularly effective on curved surfaces while maintaining excellent performance on flat surfaces.
Q: Can I use this for mounting a camera on a curved car windshield?
A: Yes, this concave vacuum cup is specifically designed to attach to both flat and curved smooth, nonporous surfaces, making it ideal for vehicle camera mounts on windshields or body panels.
Q: What surfaces will this vacuum cup hold to?
A: This vacuum cup attaches to smooth, nonporous surfaces including glass, polished metal, plastic, painted automotive surfaces, and other non-textured materials.
Q: What weight can it safely support?
A: This vacuum cup has a load capacity of 40 lbs (18kg) when properly attached to a suitable surface.
Q: How do I know if the suction is failing?
A: The cup features a red-line indicator that warns you of any vacuum loss, allowing you to take action before the mount fails.
Q: Can I reuse this vacuum cup multiple times?
A: Yes, this is a reusable vacuum mount that can be attached and removed repeatedly without drilling holes or leaving permanent marks on surfaces.
Q: Can I add more suction without starting over?
A: Yes, the check valve allows you to re-pump and add vacuum pressure without losing the remaining vacuum that's already established.
Q: How do I remove the vacuum cup quickly?
A: The vacuum pad has lift tabs on the edges that permit instant release when you need to remove the mount.
