Medium to high load capacity hangers designed to carry 2 or 3 trusses. Accommodates right or left hand hips (at 45-degree skews) and can be used for terminal hips with or without the center common jack. The MTHM-2 accommodates 2-ply hips or jacks.

Material: 12 gauge.

Finish: Galvanized

Installation:

Use all specified fasteners. See General Notes.
All multiple members must be fastened together to act as a single unit.
Shall be attached to a double girder truss to allow for required minimum nail penetration. See footnote 7.

Allowable loads have been increased 33% and 60% for earthquake or wind loading with no further increase allowed; reduce
where other loads govern.
Hip loads are for each hip.
Roof (125/133/160) is a download rating.
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.
Combine hip and jack loads for total capacity. For terminal hips divide the total allowable load by 2 to determine the allowable load for each hip.
Truss chord cross-grain tension may limit allowable loads. Refer to Technical Bulletins T-ANSITPISPF, T-ANSITPISP
and T-ANSITPIDF for allowable loads that consider ANSI/TPI 1-2002 wood member design criteria.

With single 2x carrying members, use 10dx1 1/2" nails with 0.67 of the table values.
For terminal installation, distribute 40% of total load to each hip member and 20% to the jack.
Tabulated hip and jack 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.
NAILS: 16d = 0.162" dia. x 3 1/2" long, 10dx1 1/2 = 0.148" dia. x 1 1/2" long. See other nail sizes and information.
