Product Overview
PA28 Purlin Anchor
Purlin anchors offer solutions for wood-to-concrete and concrete-block connections which satisfy code requirements. The HPA offers the highest capacity in concrete. The PAÂ’s dual-embedment line allows installation in concrete or concrete block.
Material:
PA — 12 gauge; HPA — 10 gauge
Finish:
Galvanized (G90)
Installation:
Use all specified fasteners; some models have extra fastener holes. See General Notes.
Purlin anchor must hook around rebar.
Allowable loads are for a horizontal installation into the side of a concrete or masonry wall.
Strap may be bent one full cycle (bent vertical 90° then bent horizontal).
PA51/PA68 — for additional length, an MST strap can be attached using 1/2" bolts through existing holes.
Refer to technical bulletin PA Foundation Straps for Uplift Resistance (T-PAUPLIFT) for additional information.
Edge Distance — minimum concrete edge distance is 5". Minimum concrete block left-to-right edge distance is 20".
Concrete Block Wall — the minimum wall specifications are:
A — one # 4 vertical rebar, 32" long, 16" each side of anchor B — two courses of grout-filled block above and below the anchor (no cold joints allowed) C — a horizontal bond beam with two #4 rebars, 40" long, a maximum of two courses above or below the anchor D — minimum masonry compressive strength, f'm = 1,500 psi
Options:
See LTT, HTT and S/LTT, S/DTT tension ties for alternate retrofit solutions
