Typical THJM Installation
The new THJM is a non-welded hanger designed to carry
radial-end jack framing and provide optimal efficiency for those
multi-plane, angled bay roofs over breakfast, study and library
alcoves. The unique patent pending design of the THJM accom-
modates 2x4 girder bottom chords and uses our Strong-Drive
®
SDS screws for easy installation with minimal fasteners.

The DSC drag-strut connector transfers the diaphragm shear
forces from the girder truss or beam to the shearwalls. The new
DSC5 has been designed to optimize fastener location, resulting
in a connector that outperforms the DSC4 with fewer fasteners. The
DSC2 is a smaller, lighter version that installs with fewer screws.

CODES: See page 13 for Code Reference Key Chart.
1. Tabulated loads are the total allowable loads of all carried members combined;
the load on any single carried member shall not exceed 25% of the total published
load for the THJM2-4 or 20% of the total published load for the THJM2-5.
2. Uplift loads have been increased for wind or earthquake loading with no
further increase allowed. Reduce where other loads govern.
3. A minimum 2-ply carrying member is required for the SDS
1
⁄ 4 "x3" screws
(provided). For single 2x carrying members, use SDS
1
⁄ 4 "x1
1
⁄ 2 " screws (not supplied)
with corresponding loads.
4. A minimum 2-ply carrying member is required for the tabulated loads.
5. Truss chord cross-grain tension may limit allowable loads per ANSI/TPI 1-2007.
The optional triangle holes may be used for installation on 2x6 and larger carrying
members, for a total of 10 fasteners into the carrying member, to resist cross-grain
tension forces when no other mechanical reinforcement is available.
6. Tabs on the seats of the THJM hangers have obround holes for optional 10dx1
1
⁄ 2 " slant
nails (2 per carried member) when additional uplift capacity is required. Total allowable
uplift with the optional 10dx1
1
⁄ 2 " slant nailing is 970 lbs. (DF/SP/SPF/HF).
