Mudsill anchors have always been a time-saving alternative to anchor bolts, and the MASA anchors provide even greater load-carrying capacity alternative for 5/8" and 1/2" mudsill anchor bolts on 2x, double-2x and 3x mudsills. It also eliminates the need for 3" square plate washers for seismic design and, in some cases, has load capacities that meet or exceed the parallel and perpendicular to plate shear capacity of other cast-in-place anchors. Two versions of the MASA are available – the standard MASA for installation on standard forms and the MASAP for panelized forms. The MASA and MASAP are code listed by ICC-ES under the 2006, 2009 and 2012 IBC® and IRC® and have been tested to meet the requirements of ICC-ES acceptance criteria AC-398 for cracked and uncracked concrete.

• Use all specified fasteners (included).
• Concrete shall have a minimum f'c = 2500 psi.
• Spalling—Full loads apply for spalls up to a maximum height of 1 1/4" and a maximum depth of 7/8". Any exposed portion of the mudsill anchor must be protected against possible corrosion.
• For prescriptive anchor spacing see table.
• Testing shows that these mudsill anchors can be used in lieu of code-required anchor bolts and square washer in high seismic zones. Refer to flier Easier Mudsill Anchoing: Cast-in-Place Mudsill Anchor (F-MASA) for additional information.
• Minimum MASA end distance is 4" and minimum center-to-center spacing is 8" for full load.
• For continuous load path, MASA should be installed on the same side of wall as uplift connectors.

NOTE: The correct fasteners installed in the correct position must be used to achieve published load values
