Key Features

Adjusts On Site

The field-adjustable body bends from 0 degrees to 135 degrees, so you can fit intersecting wood members without fabricating a custom clip angle. That saves time when framing around hips, rafters, and awkward tie-in points.

ZMAX Protection

ZMAX galvanized steel adds extra corrosion resistance for exterior use and treated-wood applications. If the connection is exposed to weather or harsher jobsite conditions, that finish matters.

LS70Z Wood Connector

The Simpson Strong-Tie LS70Z Adjustable L-Angle uses defined fastener locations and a 6-3/8 inch body to make wood-to-wood connections more consistent. It is a practical choice for roof framing, repairs, and general reinforcing work.

Overview

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.

Fits Angled Connections Without Custom Fabrication

If your framing members meet at an odd angle, the LS70Z gives you adjustment range instead of forcing you into a fixed bracket. That makes it a practical fix for rafters, braces, repairs, and other wood connections that rarely land at a perfect 90.

• Field-adjustable from 0 degrees to 135 degrees
• Ships at 45 degrees and should be bent one time only

Designed for Real Framing Work

This is not just a generic repair plate. The LS series is used where wood members intersect at angles, including rafter-to-hip rafter connections. Defined hole locations help keep the connection repeatable and easier to install cleanly.

• Application: wood-to-wood fastening
• Use all specified fasteners for the intended connection

Size That Matches the LS70Z Connector

The LS70Z gives you a longer body than smaller LS series angles, which is why it is a better fit when you need more reach along the members being tied together. That added length can help when the connection needs more coverage than a compact repair angle can provide.

• Connector length: 6-3/8 inches
• Series illustration shows 2-1/4 inch leg dimensions

Pro Tip

Dry-fit the angle before you fasten it, because Simpson Strong-Tie specifies bending it one time only. If you are using a single LS connector in the connection, make sure the joist is blocked or otherwise restrained against rotation.

Tool Nut’s Take

Simpson Strong-Tie LS70Z Adjustable L-Angle: the easy answer for awkward wood connections

This is the kind of connector that earns its keep when a standard angle will not line up and you do not want to waste time making your own bracket.

• Who it’s for: Framers, remodelers, deck builders, and DIY users dealing with angled wood-to-wood connections.
• Why it stands out: The bendable LS body, defined fastener locations, and ZMAX corrosion resistance make it more useful than a generic hardware-store angle.
• Worth knowing: It is bend-once hardware, not a reusable adjustable bracket, and fasteners are not included.

Common Questions

• Is the LS70Z a fixed 90 degree angle? No. It is field-adjustable from 0 degrees to 135 degrees and ships at 45 degrees.
• What materials is it designed to connect? It is designed for wood-to-wood fastening applications.
• What fasteners does it use? Product data specifies 10d common nails or #9 x 1-1/2 inch Strong-Drive SD screws.
• Can it be used with treated lumber or outdoors? The ZMAX finish is intended for extra corrosion resistance in exterior and treated-wood applications, and the connector is listed as ACQ approved.
