LTP4/LTP5/A34/A35 Framing Angles and Plates
The larger LTP5 spans subfloor at the top of the blocking or rim board. The embossments enhance performance.
The LTP4 lateral tie plate transfers shear forces for top plate-to-rim board or blocking connections. Nail holes are spaced to prevent wood splitting for single and double top-plate applications. May be installed over plywood sheathing.
The A35 angle's exclusive bending slot allows instant, accurate field bends for all two- and three-way ties. Balanced, completely reversible design permits the A35 to secure a great variety of connections.

Load Values with Carbon Steel Nails
These products are available with additional corrosion protection. Additional products on this page may also be available with this option, check with Simpson Strong-Tie for details.
These models are approved for installation with the Strong-Drive® SD Connector screw. See the load values below.
- Allowable loads are for one angle. When angles are installed on each side of the joist, the minimum joist thickness is 3".
- Some illustrations show connections that could cause cross-grain tension or bending of the wood during loading if not reinforced sufficiently. In this case, mechanical reinforcement should be considered.
- LTP4 can be installed over 3/8" wood structural panel sheathing with 8d x 1 1/2" nails and achieve 0.72 of the listed load, or over 1/2" and achieve 0.64 of the listed load. 8d commons will achieve 100% load.
- LTP4 satisfies the IRC continuously sheathed portal frame (CS-PF) framing anchor requirements when installed over raised wood floor framing per Figure R602.10.6.4.
- The LTP5 may be installed over wood structural panel sheathing up to 1/2" thick using 8d x 1 1/2" nails with no reduction in load.
- Connectors are required on both sides to achieve F2 loads in both directions.
- A34 and A35 installed with 8d x 1 1/2" nails onto 1 1/4" LSL material will achieve 0.90 of the listed F1 and F2 loads.
- Fasteners: 8d x 1 1/2" = 0.131" dia. x 1 1/2" long; SPAX #6 x 1/2" = 0.138" dia. x 1/2" long.
