4in Suction Cup w/Flange
The DLC Vacuum Cup Mounts are heavy duty vacuum cup mounts designed with durability and utility in mind with the ability to support more weight than most mounts will, up to 50 lbs. The built-in Wood’s style hand pump allows the vacuum cup to get a firm grip on a smooth surface. Just a few strokes of the plunger evacuates the air from the vacuum pad, causing it to seal securely to the surface it is being attached. When the cup is attached completely, the red line on the plunger disappears under the sleeve and the plunger stroke becomes very short. A safety feature of this design is that if the red line reappears, it indicates that the seal has become insecure and the unit needs to be secured again. The pad features 2 release nibs near the edge of the pad. Just push on the nib from the outside of the pad to release the seal. Complete with protective cap to prevent scratching of the cup surface.
