MMLU210 Face Mount Hanger
MMLU210 Face Mount Hanger

The face-mount MMLU series provides installation versatility for factory-built structures. Nailing grids in the MMLU hangers replace traditional nail holes, allowing for faster installation of power-driven nails. Each hanger provides multiple nailing pattern options to enable value engineering for different loads.

Key Features:

Versatile fastener placement enables faster installation, ideal for modular building settings

Designed with factory-used tools in mind

Built specifically for optimal fastening using a power nailer


MMLU26-2, MMLU28-2 18 gauge, all others 20 gauge


Galvanized (G90)


Nails must be installed with a powered nail tool. Face protection is required. To reduce ricochet, install nails straight through the nailing grid. Follow all safety instructions for the nail tool.

Adjust the nail tool pressure so nail heads are flush with the hanger and are not overdriven causing the MMLU steel to dimple.

Install at least one 8d x 1 1/2" or 10d x 1 1/2" nail into each nailing grid.

Install additional nails in accordance with the MMLU Installation and Load Table for increased capacity. Each header nailing grid must contain the same quantity of nails.

The minimum vertical center-to-center spacing of nails in the same nailing grid is 1/2" and must not split the wood header.

The MMLU height (H) must equal or exceed 60% of the joist height to provide joist rotation resistance. If H is less than 60% of the joist height, provide lateral restraint to the top of the joist by other means, such as blocking, end nailing or Simpson Strong-Tie A34 framing angles above the hanger.

I-joist web stiffeners or floor truss end vertical webs must be installed in the carried member when the hanger side flanges do not support the I-joist top flange or floor truss top chord.
