SquiJig Buying Guide

Introduction

SquiJig makes measuring tools that just work harder than everything else. Born from a builder's frustration – if it's needed and doesn't exist, build it – SquiJig has earned its place as the go-to brand for framers, carpenters, metal fabricators and anyone who needs precision without compromise.

Their rafter squares and framing jigs are obsessed over on job sites for good reason: they're beautifully engineered, built to last years, and they genuinely speed up your workflow.

This guide covers everything you need to know about SquiJig's range, from their bestselling Fusion PRO squares to their game-changing framing jigs. Whether you're after your first rafter square or looking to complete your measuring setup, we've got you covered.

The Brand

SquiJig was founded in 2017 by Sven in Portland, Oregon. It's a small, family-run business with a big passion for building tools that last. Every SquiJig product is made in the USA and designed with input from actual builders – the kind of people who use these tools every single day and aren't afraid to tell you when something isn't working.

The ethos is refreshingly simple: if a tool is needed and doesn't exist, build it. If it exists and can be better, make it better. This philosophy shows in every product – from the crisp laser markings to the patented design features that solve real problems on site.

Pros & Cons

PROS	CONS
Made in USA – crafted with serious attention to detail Rafter squares feature ultra-visible 360° vials and crisp laser markings Patented features you won't find elsewhere (like the wench on the heel for blade adjustments) Framing jigs grip onto your work piece and stay put – no slipping Wide colour range means your tools are easy to spot on site Small family business with genuine customer care	Higher price point than budget alternatives (but worth every penny) If you prefer imperial over metric, stock can be more limited Learning curve for framing jigs if you're used to traditional gauges – but that's a feature, not a bug Limited product range compared to larger tool companies (they focus on what they do best)

Core Ranges

Squares

SquiJig's rafter squares are precision instruments built for framers, roofers, and deck builders. The Fusion PRO 7.5" is the flagship – it features an ultra-visible 360° level vial, built-in 13mm & 14mm blade wrenches, a patented wench on the heel for blade adjustments, and scribe notches designed to grip your pencil. Available in both metric and imperial with an awesome range of colours (black, orange, green, red, blue, pink). 

For those needing a pocket-sized option, the Mini Fusion Pro 4.5" delivers all the precision in a compact size. Perfect for second fix and trim work, it's available with a 3/16" heel (no level vial) or a 9/16" heel with level vial built in. Colours include black, green, orange and pink.

Jigs

SquiJig's framing jigs come in two sizes for different trades. The 1.5" framing jigs are the workhorse for carpenters – clamp onto your speed square or framing square and use for stair gauges, stair layout, rafter layout, and as a rip guide on your saw. The taller profile gives a solid hold on the workpiece. Available in blue and red as a pair.

For metal fabricators and steel workers, the 3" framing jigs feature a unique cylinder design with dual slots, giving unlimited positioning options. They overcome rounded edges on square tube, act as a third hand when tacking, and keep your square standing upright on large metal beams.

Complete your jig setup with the framing jig holder – made from strong ABS plastic, it clips to your tool belt or vest and holds two jigs (either size), so you'll never lose your gauges in your toolbox again.

Top Picks

The Customer Bestseller

SquiJig Fusion PRO 7.5" Rafter Square

Why it sells: This is the square that people come back for and tell their friends about. The 360° level vial is genuinely ultra-visible – you'll spot it from across the site. The crisp laser markings are easy to read even in poor light. But the real game-changer is the patented wench on the heel that lets you adjust your blade without fumbling for a spanner. Customers say it's an investment that pays for itself in time saved and frustration avoided. Available in both metric and imperial, plus a cracking range of colours.

TF Recommendation: The Unsung Hero

SquiJig Framing Jig Holder

Why we recommend it: If you own framing jigs, you need this. It's made from real hickory hardwood and holds two jigs securely whilst clipping easily to your belt. Pros cite it as one of the smartest accessories they own – it keeps your gauges safe, organised and within arm's reach. No more digging through your toolbox on site. It's simple, beautifully made, and solves a real problem.

Frequently Asked Questions

Q. What's the difference between the 1.5" and 3" framing jigs?

A. The 1.5" jigs are designed for carpenters working with wood – they overcome defects in lumber and are perfect for stair gauges, rafter layout and saw guides. The 3" jigs have a metal fabrication background. Their weight and size help the framing square stay upright on large metal beams, and the dual slots let you work around brackets, welds and other obstacles. Choose based on your primary material.

Q. Do I need both metric and imperial squares?

A. Most UK builders work in metric, so a metric square is your standard choice. However, if you're working with imperial measurements, SquiJig makes both – and interestingly, the imperial squares are slightly cheaper due to higher US batch quantities. If you're doing both types of work, having one of each is smart.

Q. Are these squares suitable for beginners?

A. Absolutely. While they're serious tools made for professionals, the precision and ease of use actually make them great for learning. The level vial and crisp markings give you confidence in your measurements.

Q. What does the 'patented wench' do on the Fusion PRO?

A. The built-in 13mm & 14mm wench on the heel lets you adjust your blade without needing a separate tool. It's a small feature that saves frustration on site and keeps your tool count down.

Q. Are there bundles available?

A. Yes! SquiJig offers several bundles – like the Fusion PRO paired with 1.5" framing jigs, and the Framing Jig & Holder bundle. Bundles offer great value if you're setting up a complete measuring kit.
