Suction Cup Mount with 4 1/2 in Cup

The Powr-Grip LJ45AMP1420T38L is a single-cup suction mount built for lifting, pulling and conveying tasks. Its concave rubber cup grips both flat and curved surfaces, while a threaded 1/4 in.-20 stud provides a secure attachment point. A pull-tab release mechanism allows quick removal without tools. The unit ships with a vacuum pad protector and is rated for a maximum load of 40 lb.

Temperature and Surface Limits

The mount operates reliably between 0 and 120 degrees Fahrenheit, so it suits typical workshop and outdoor conditions. Adhesion depends on clean, non-porous surfaces; dust, oil or heavy texture will reduce holding power. The concave cup profile helps conform to gentle curves, but sharply radiused or highly irregular shapes may prevent a full seal. Users should verify surface suitability before relying on the rated capacity.

40 lb Maximum Load Capacity

The 40 lb limit is the single figure that determines whether this mount fits the job. Loads exceeding this value risk sudden release, especially if the surface is not perfectly smooth or if temperature extremes affect rubber flexibility. For heavier items, a multi-cup system or mechanical clamp is required. Always test the mount with a light load first to confirm adhesion on the specific surface.
