Designed primarily for concealed use, this versatile hold-down can be used anywhere you can drill a 3/4" diameter hole. Its post has a wedging mechanism controlled by a swivel handle to anchor it firmly (in any orientation) in throughholes in material as thin as 5/8" (depending on the strength of the material) or in blind holes (for concealed applications) a minimum of 1-1/4" deep. With a 5" long threaded post, and a large diameter wing nut for tightening, it can be used on work surfaces up to 4-1/8" thick through a 1/2" diameter or larger dog hole. Weight: 255g.
