MASA/MASAP Mudsill Anchors
Concrete Connectors

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 bottom tracks, the MASA 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, 2012 and 2015 IBC® and IRC® and have been tested to meet the requirements of ICC-ES acceptance criteria AC-398 for cracked and uncracked concrete.
Material
- 16 gauge
Finish
- Galvanized. All available in ZMAX® coating. See Corrosion Information.
Installation
- Use all specified fasteners; see General Notes.
- MASA/MASAP
– Concrete shall have a minimum f'c = 2,500 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.
– 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.

Load Tables
Allowable Loads for MASA/MASAP Cast-in-Place Mudsill Anchor on CFS Track
- Allowable loads are governed by tests and may not be increased (CD = 1.0).
- The tabulated allowable (ASD) loads may be multiplied by 1.6 for designs for wind and in SDC A&B, and by 1.4 for designs in SDC C through F to obtain the LRFD loads.
- Minimum concrete compression strength, f'c is 2,500 psi.
- Allowable loads are based on a minimum stemwall width of 6".
- For simultaneous loads in more than one direction, the connector must be evaluated using the Unity Equation.
- Per Section 1613 of the 2009, 2012 and 2015 IBC, detached one- and two-family dwellings in SDC C may use the "Wind and SDC A&B" allowable loads.
- Parallel-to-Track loads for One-Leg-Up Installation: SDC A–C = 1,025 lb., SDC C–F = 860 lb.
- See more information on Simpson Strong-Tie fasteners.
