Swanson SW1201K Speed Square Value Pack: 7" and Big 12 Bundle

Swanson's SW1201K bundles their iconic 7-inch and Big 12 speed squares with the Blue Book guide — a practical combination for framers and hobbyists who want both sizes without buying separately.

Two squares for the price most brands charge for one

Swanson has been making speed squares since they invented the thing in 1925, so there's real pedigree here. The 7-inch is the standard jobsite companion — fits in an apron pocket, handles rafter layout, quick 90s and 45s all day. The Big 12 is the one you reach for on wider stock, stair stringers, or anywhere the smaller square just doesn't span enough material. Getting both plus Swanson's Blue Book (a legitimate rafter table reference, not just a marketing insert) in one order at this price point is a straightforward win for anyone who's been making do with just one size.

Worth knowing before you order

The Big 12 in this kit ships without the layout bar — that's the sliding fence attachment some users expect from the full version. If you're doing repetitive production framing where that bar saves real time, you'd want to check whether you're okay without it or budget for it separately. For most DIYers and light-duty framers, it won't matter at all. These are aluminum squares, not the thicker cast or steel options some pros prefer for durability under heavy use, but for the price and everyday accuracy, Swanson's tolerances hold up well in practice.
