What is the minimum distance of adjustable assemblies from the brick edge?

• A. 1/2 inch
• B. 5/8 inch
• C. 3/4 inch
• D. 1 inch

Answer: (B)

This question tests the minimum clearance needed between an adjustable assembly and the brick edge to allow proper installation and operation without contacting the brick. Five-eighths of an inch is the recommended minimum because it provides enough room for the adjustable hardware to sit and move without bearing on the brick, while also accommodating mortar joints, sealant, and flashing behind the veneer. It helps prevent damage to the brick edge during adjustment and installation, and keeps the assembly aligned with the brick face as the wall settles or tolerances vary. A tighter gap like half an inch would be too close and risk interference, while larger gaps such as three-quarters or one inch waste space and can complicate alignment.
