FAQ
When should I use a sleeve anchor?
Use it for medium loads in brick, block, or concrete where a wedge anchor might crack the material — railings, brackets, and general masonry fastening.
Sleeve anchor drill size?
Drill the hole to the anchor diameter (e.g. 3/8 in anchor = 3/8 in bit) and blow out the dust before inserting.
