LMAZ/MAB/MASB Mudsill Anchors

Product Details

Mudsill anchors provide an alternative to anchor bolts. They easily mount on forms and make finishing easier. The unique design provides installation flexibility, eliminating problems with misplaced anchor bolts. Suitable for stemwall or slab foundations, mudsill anchors are one piece so there are no more nuts and washers to lose.

LMAZ — an economical replacement for 1/2" sill plate anchor bolts
MAB/MASB — anchors mudsill to concrete block, poured walls or slab foundations

Material

LMAZ, MAB — 18 gauge; MASB — 16 gauge

Finish

MAB, MASB — galvanized (also available in ZMAX® coating); LMAZ — ZMAX only. See Corrosion Information.

Installation

Use all specified fasteners; see General Notes.
LMAZ/MAB:

CMU shall have a minimum f'_m = 1,500 psi and concrete shall have a minimum f'_c = 2,000 psi.
Not for use where a horizontal cold joint exists between the slab and foundation wall or footing beneath, unless provisions are made to transfer the load.
Not for use in slabs poured over foundation walls formed of concrete block or with brick and 4" masonry block stemwalls.

MASB:

Fill CMU cell with concrete grout first, then place MASB into the grouted cell and adjust into position. Attach mudsill to anchor only after the concrete grout cures.
CMU shall have a minimum f'_m = 1,500 psi.
The MASB Mudsill Anchors were tested in standard 8" CMU.

These products are available with additional corrosion protection. Additional products on this page may also be available with this option, check with Simpson Strong-Tie for details.

"Prescriptive" denotes designs per the IRC or conventional provisions of the IBC for wind speeds 100 mph or less, or for Seismic Design Category D and less (SDC E and less in IBC).
Spacing is based on parallel to plate load direction only.
Place anchors not more than 12" from the end of sill and splices per code.
CMU shall have a minimum f'm = 1,500 psi and concrete shall have a minimum f'c = 2500 psi.
Spacings apply to DF, SP, and HF sill plates.
