The Simpson Strong-Tie 3-3/8-in. 18-Gauge ZMAX Galvanized Adjustable L Angle (LS30Z) is a skewable reinforcing angle for wood-to-wood fastening. This is an adjustable L angle designed for connecting wood members that meet at standard or offset angles. Model Number: LS30Z. If you need a compact connector for repairs, bracing, or tying rafters together without making a field-built clip, this one keeps the job simple.

What separates the LS30Z from a basic fixed bracket is adjustability. It can be field-adjusted from 0° to 135°, which gives you room to handle connections where framing does not land at a perfect 90°. That makes it useful for roof framing details like connecting roof rafters to hip rafters, and it also makes sense for general repair work where the existing structure is not perfectly square.

The 3-3/8 in. length puts this model on the compact end of the LS series, so it fits smaller connections where you still want a load-rated metal angle instead of relying on toenails or improvised hardware. Simpson Strong-Tie also calls out well-defined fastener locations and tabulated load values designed to account for connection eccentricities. In plain terms, the hole pattern is laid out to give you a more controlled connection than guessing nail placement in the field.

Material matters here. The LS30Z is made from 43 mil, 18-gauge steel, which is substantial enough for reinforcing duties while still being bendable on site. The ZMAX finish is the version to look for when the connector may see more moisture or contact with treated lumber. For exterior repairs, deck-related framing tie-ins, or roof work where corrosion is a real concern, that coating is one of the main reasons to step up to the Z model.

Installation is straightforward, but there are a couple of details worth paying attention to. Simpson specifies that the angle is field skewable and should be bent one time only. The manufacturer also notes that you should use all specified fasteners, and when using a single LS per connection, the joist must be constrained against rotation, such as with solid blocking. That is the kind of detail that keeps a connection working the way the load table intends.

For fastening, the listed options include 10D common nails or #9 x 1-1/2 in. Strong-Drive SD screws. That gives you flexibility depending on access, job conditions, and how you prefer to install connectors. Either way, this is a purpose-built framing bracket, not a generic flat mending plate. It is meant for structural wood connections where the angle and fastener pattern both matter.

This adjustable angle is a strong fit for carpenters, remodelers, general contractors, and serious DIY users doing framing repairs, roof framing tie-ins, or utility reinforcement around the house. If your work regularly involves wood members meeting at something other than a clean right angle, the LS30Z saves time and gives you a cleaner answer than trying to force a fixed connector to do a job it was not made for.

Simpson Strong-Tie 3-3/8-in. 18-Gauge ZMAX Galvanized Adjustable L Angle (LS30Z) is the right fix when a standard angle will not line up

This is a smart little framing bracket for anyone who wants a cleaner, more dependable angled wood connection without making parts in the field.

• Who it's for: Carpenters, remodelers, roof framers, and serious DIY users working on wood-to-wood connections that land at odd angles.
• Why it stands out: The 0° to 135° adjustability, compact 3-3/8 in. size, and ZMAX coating make it more useful than a basic fixed-angle bracket for outdoor and treated-lumber work.
• Worth knowing: It is bend-one-time-only hardware, so layout matters. If you install connectors for a living, that is not a downside, just something to respect.

• What is the LS30Z used for? It is used for wood-to-wood fastening, including connecting roof rafters to hip rafters and other reinforcing jobs where members meet at an angle.
