Simpson Angles & Plates (Models LTP4, LTP5, A34, A35)

Simpson Strong-Tie Angles & Plates (Models LTP4, LTP5, A34, A35)

Simpson Strong-Tie Angles & Plates provide versatile solutions for a wide range of wood framing applications. The LTP series lateral tie plates are engineered to transfer shear forces in top-plate-to-rim-board or blocking connections, with staggered nail patterns that reduce the risk of wood splitting and allow installation over plywood sheathing. These plates save time on the job while ensuring reliable performance in both single and double top-plate assemblies.

The A34 and A35 framing angles are designed to create strong 90° connections between framing members. Both angles are load-rated for wind and seismic forces, with the A35 featuring a bending slot for precise field adjustments. Made from galvanized steel for corrosion resistance, these connectors simplify installation and provide durable, code-compliant support for new construction or retrofit projects.

Simpson Strong-Tie Angles & Plates

Simpson Strong-Tie angles and plates are engineered to simplify framing connections while providing reliable structural support. These galvanized steel connectors come in 18- and 20-gauge options, offering a durable, corrosion-resistant solution for wood construction. From transferring shear loads in roof diaphragms to holding multiple framing members together at precise angles, these connectors streamline installation and enhance structural integrity.

Whether you’re working on new construction or retrofitting an existing structure, these connectors save time on the job site while maintaining code-compliant performance. They are suitable for single and double top-plate applications, rim-board connections, blocking, and a variety of other framing scenarios.

LTP Lateral Tie Plate

The LTP series is specifically designed to manage lateral loads in framing assemblies. By transferring shear forces between plates, rim boards, or blocking, these plates help keep structures rigid under stress. Their staggered nail patterns minimize splitting, and the plates can be installed directly over plywood sheathing or fastened straight to framing members.

Why Use LTP Plates?

Load-rated for shear forces to ensure structural safety
Optimized nail hole spacing to reduce wood splitting
Flexible installation options over plywood or direct-to-framing

Applications include roof diaphragm connections, plate-to-rim board assemblies, and blocking reinforcement in walls.

Framing Angles: A34 & A35

A34 Framing Angle

The A34 is a versatile framing angle for general-purpose connections. Designed with a speed prong to temporarily hold it in place, it makes installation straightforward, especially in retrofit scenarios. This angle is load-rated for both wind and seismic forces, giving builders confidence in high-stress environments.

Key Benefits:

Fast, secure installation with nails or SD screws
Speed prong design holds the angle during fastening
Compatible with new builds or retrofits

A35 Framing Angle

The A35 takes versatility a step further with a reversible design and exclusive bend slot. Field bends can be made quickly and accurately, allowing the connector to serve as two- or three-way tie points. Like the A34, it is load-rated for wind and seismic conditions and can be fastened using nails or screws.

Key Benefits:

Instant field-bend capability for flexible connections
Reversible design for multiple applications
Speed prong ensures easy temporary positioning

Frequently Asked Questions

Can LTP plates be installed over plywood sheathing?

Yes. The plates are designed to be installed directly over plywood sheathing or attached to framing members for flexible use.

What applications are A34 framing angles used for?

A34 angles are ideal for 90° wood-to-wood connections, such as wall-to-wall or beam-to-post joints.

What makes the A35 framing angle different from the A34?

The A35 features a bend slot that allows instant field bending for two- and three-way ties, offering more versatility for complex connections.

Do these connectors work with LVL or PSL beams?

Yes, provided the fasteners are compatible and installed according to load tables and manufacturer guidance.

Can I combine LTP plates with other Simpson connectors?

Yes. They are compatible with most Simpson Strong-Tie framing products, making them easy to integrate into larger structural systems.

My LTP plate keeps splitting the top plate. What can I do?

Use staggered nail holes and pre-drill pilot holes for dense lumber. Ensuring correct fastener spacing also helps prevent splitting.

My truss or rim board is slightly off. Can A35 adjust for this?

Yes. The bend slot allows field adjustment to accommodate minor misalignments without cutting or modifying the wood.
