MTHMQ/MTHMQ-2 Multiple Truss Hangers
The MTHMQ and MTHMQ-2 are redesigned versions of our medium-to-high load capacity hangers for carrying 2 or 3 trusses. The new design offers concealed flanges and installs with Strong-Drive® SDS screws for easier installation.
Features:
- Accommodates right or left hand hips (at 45° skews) and terminal hips with or without the center jack
- Strong-Drive® SDS screws (included) are easy to install and enable the hangers to achieve higher loads with fewer fasteners
- Concealed-flange design allows for attachment to vertical web members
- Min. and max. fastening options for added versatility
Material: 12 gauge.
Finish: Galvanized (G90)
Installation:
- See General Notes.
- Use the Strong-Drive SDS screws provided with the hanger.
- Can be installed filling round holes only, or filling round and triangle holes for maximum load. For all installations, fill the fastener holes in the bottom of the hanger seat.
- For installations at panel points with 2x6 bottom chords, do not fill the triangle holes unless approved by the Truss Designer.

Right or Left Hand Hip Installation (Two-Member Connection) 3,4
Terminal Type Installation (Three-Member Connection)5
- Allowable loads have been increased for wind or earthquake loading with no further increase allowed; reduce where other loads govern.
- minimum 2-ply carrying member is required for the tabulated loads. With single 2x carrying members, use 1/4"x1 1/2" Strong-Drive® SDS screws into the carrying member and reduce the load to 0.60 of the table value.
- For installations on 2x6 carrying members not at a panel point, the four uppermost face fasteners are not installed. For installations on 2x6 carrying members at a panel point, fasteners are installed into the round holes only (minimum vertical member sizes are 2x6 and 2x8 for the MTHMQ and MTHMQ-2, respectively).
- Tabulated two-member allowable loads assume that 75% of the total load is distributed to the hip and 25% to the jack. It is permitted to distribute 65% to 85% of the tabulated total load to the hip, and the remaining percentage of total load to the jack. The combined hip and jack load may not exceed the published Total Load.
- For terminal hips divide the total allowable load by 2 to determine the allowable load for each hip.
- Tabulated three-member loads assume that each hip carries 40% of the total load and the jack carries 20% of the total load. Other hip/jack load distributions are allowed if the sum of all three carried members does not exceed the total load and the hip members are equally loaded.
- The total allowable download for the MTHMQ-2-SDS3 (Min) for a 3-member connection at the 115/125/160 load duration is 5400 lbs. (DF/SP) and 3890 lbs. (SPF/HF).
- Truss chord cross-grain tension may limit allowable loads in accordance with ANSI/TPI 1-2007.
- Simpson Strong-Tie Strong-Drive screws are permitted to be installed through metal truss plates as approved by the Truss Designer, provided the requirements of ANSI/TPI 1-2007 Section 7.5.3.4 and 8.9.2 are met (pre-drilling required through the plate using a maximum of 5/32" bit).
