5-Inch Heavy Duty Lever-Lock Suction Cap with M8 Female Thread

The Spacetek 5-inch heavy duty lever-lock suction cap gives you a reusable temporary mounting point on smooth, non-porous surfaces. It is useful when you need to attach a compatible M8 bracket, hook, light accessory, camera bracket, sign or test fixture without drilling holes or using adhesive. The built-in M8 female thread accepts compatible M8 threaded hardware, making it a handy no-drill option for caravans, RVs, 4WDs, workshops, field testing and temporary display setups. ⚠️ This is a temporary suction-based mounting accessory. It must not be treated as a permanent, structural or load-critical fixing.

Installation Overview Clean the mounting surface thoroughly to remove dust, moisture and oils. Place the suction cap firmly against a smooth, non-porous surface. Engage the lever-lock mechanism to create the suction hold. Attach compatible M8 hardware to the female thread. Check the hold before attaching equipment and re-check regularly during use. Release the suction cap when finished and store it clean. Important Notes ⚠️ Holding performance depends on surface condition, surface cleanliness, load angle and environmental conditions. ⚠️ Always test the hold before use and re-check regularly. ⚠️ Do not use for overhead lifting, safety-critical mounting or permanent installations. ⚠️ Use in motion is at your own risk.
