Wood-to-concrete and wood-to-CMU connectors that satisfy code requirements. The PA’s dual embedment line allows installation in concrete or concrete block.

Material: MPAI - 14 ga; PAI - 12 ga.

Finish: Galvanized. Some products available HDG or ZMAX® coating .

Installation:

• Minimum concrete strength is 2000 psi.
• Use all specified fasteners; some models have extra fastener holes. See General Notes.
• Wood splitting may occur when anchor is nailed to wood less than 3 1/2" wide. To reduce splitting for widths less than 3 1/2", fill every other nail hole with 10dx1 1/2" nails. Reduce the allowable load based on the size and quantity of fasteners used. (See nail table.)
• PAI is designed for wood I-joists. Nail spacing is for 10dx1 1/2" nails 3" on center, to minimize the chance of wood splitting. Maximum ledger width for full loads is 1 1/2".

Edge Distance:

Minimum concrete edge distance is 5". Minimum concrete block left-to-right edge distance is 20".

Concrete Block Walls:

The masonry embedment line on PAI, MPAI allows for 4" of grout embedment in a standard 8" concrete masonry unit. The minimum wall specifications are: one # 4 vertical rebar, 32" long, at 32" o.c.; two courses of block above and below the anchor; a horizontal bond beam with two # 4 rebars, 40" long, a maximum of two courses above or below the anchor; all cells grouted with 2000 psi 3/8" aggregate grout. Grout shall be vibrated per the 1997 UBC section 2104.6.2.

Options: See LTT and HTT Tension Ties.
