Blocking a wall refers to installing a short reinforcing piece of metal framing horizontally between the vertical studs. The purpose of blocking is to provide an attachment support point for mounted construction features like handrails, shelving, frames, cabinets, railings, or other fixed hardware. T-Block offers heavy-duty blocking that significantly increases the anchor strength and stability of permanently mounted wall fixtures. Available in 16 and 20 gauge (30 mil) with standard G60 coating. Accommodates 12-, 16- and 24-inch on-center stud spacing. It fits 3 5/8-, 4-, 6-, 8-, 10- and 12-inch web sizes.
