With the Spit pro 6 universal nylon wall plug, you achieve firm and dependable fixings in both solid and hollow base materials. Whether you are working in brick, concrete, or aerated concrete, the 6-way expansion zones expand immediately and evenly to stop the plug from rotating while driving the screw. It knots securely inside cavities and delivers robust holding power in solid substrates for your heavy mounting tasks. The shallow collar keeps the 14X70 mm plug from slipping too deep into the 85 mm drill hole, ensuring a clean, flush surface finish on every installation.
