Perfect Vision PVLS516 5/16 x 1 3/4 Lag Shield - Box 50.

Drill a 1/2” O.D. hole about 2” deep in a concrete or masonry surface and insert this sleeve. Then, you can thread a standard 5/16” x 2” lag screw into the sleeve for a secure friction grip in the concrete. The PVLS516 has a gradual restriction taper inside the sleeve which expands the sleeve when the lag screw is fully seated. Very useful where wood surfaces are not available to secure the dish reflector foot or wind legs.

Features:

• Use with 3/4” or 2” wood lag screws
• Cast from Zamac(zinc) alloy
• Two-piece split body design
• Suitable for use in concrete, mortar or brick surfaces and walls

Mechanical Characteristics:

• Two piece casting. Shell haves are secured together by tabs in the casting
• Requires a 1/2” masonry drill bit for installation
• You must provide the lag screws of either 1 3/4” or 2” depending on the drilled hole depth and the material thickness you are securing
