The Simpson Strong-Tie LS70Z Adjustable L-Angle is a field-adjustable steel angle connector for wood framing and reinforcing. This is an adjustable L-angle designed for fastening wood-to-wood connections at varying angles. Model Number LS70Z. If you need to tie members together where a fixed angle bracket does not line up cleanly, this connector gives you a simpler way to make that connection without fabricating something in the field.

What makes the LS70Z useful is the adjustment range. It can be bent from 0 degrees to 135 degrees and ships at 45 degrees, which gives you room to match different intersecting member angles on site. Simpson Strong-Tie also calls out that it should be bent one time only. That matters because this is meant to be fitted once for the connection, not repeatedly reshaped.

The LS70Z is made from 18-gauge steel with a 43 mil thickness and a 6-3/8 inch length. It is part of Simpson Strong-Tie's LS series of skewable angles, which are used for general utility reinforcing as well as specific framing jobs like connecting roof rafters to hip rafters. Compared to field-fabricated clip angles, the advantage here is consistency. You get a manufactured connector with defined fastener locations instead of relying on a custom-made piece on the fly.

The ZMAX galvanized finish is one of the bigger reasons to choose this version over a basic plated connector. It is intended for added corrosion resistance, including exterior and treated-wood applications, and the product is listed as ACQ approved. For decks, exposed framing repairs, and other spots where standard steel hardware can be a weak link, that finish is doing real work.

Installation is straightforward, but the details matter. This LS angle is used for wood-to-wood fastening and is installed with 10d common nails or #9 x 1-1/2 inch Strong-Drive SD screws. The connector has 10 holes and well-defined fastener locations to help keep placement consistent. Simpson Strong-Tie also notes that when a single LS is used per connection, the joist must be constrained against rotation, for example with solid blocking.

Who is this for? Carpenters, framers, remodelers, deck builders, and serious DIY users who run into angled wood connections that do not fit a standard bracket. It is especially useful when you want a cleaner, faster solution for repairs or roof framing details, but you still want a connector from a tested structural hardware brand instead of improvising with flat stock.
