Empire 12″ Polycast Rafter Square

The Empire 12″ Polycast Rafter Square (Model 396) is an oversized polymer layout tool built for framing contractors who need a square that won’t break when dropped off a ladder. Made from Polycast® (Heavy-duty polymer material), it’s designed specifically for marking wider boards that standard 7-inch squares can’t handle.

Worth it if you’re framing with 2x12s or working with engineered lumber. Skip it if you only frame with 2x8s or smaller — the standard 7-inch version costs less and handles easier.

Why Polycast Beats Aluminum in Montana

Won’t bend or break under heavy-duty use — that’s the whole point of polymer construction. Drop an aluminum square from scaffolding onto frozen ground in February, and you might bend it. This Polycast material bounces.

The polymer construction handles Montana’s temperature swings better than metal squares. Aluminum contracts and expands with Montana’s 100-degree temperature ranges. Polycast stays dimensionally stable whether it’s -20°F or 95°F. No warping, no binding against the lumber when marking.

Lightweight and durable Polycast construction means you’re not hauling extra weight up ladders all day. The material won’t corrode from jobsite chemicals or road salt tracked onto lumber piles. It won’t leave marks on finished lumber like some metal squares do.

12-Inch Capacity Changes the Game

Extra large size ideal for use in marking wider boards — this matters when you’re laying out cuts on 2x12 joists or engineered beams. The 12 inches of marking capacity means one pass across a 2x12 instead of repositioning a smaller square.

Compatible with standard 2x lumber and wider boards up to 12 inches. That covers everything from standard framing lumber to LVLs and glulams. The 17 inches (approximate, for hypotenuse/packaging) gives you extended reach for angled cuts.

Built-In Tables Save Time

Molded-in conversion tables for quick and easy measurements put the math right on the tool. No pulling out a calculator or reference card when laying out rafters. The tables are molded into the polymer — they won’t wear off like painted markings on cheaper squares.

Easy to see graduations on both sides means you don’t flip the square constantly. The SAE graduations repeated on both sides work whether you’re right or left-handed, marking from above or below.

Standard rafter square usage: hold the lip against the board edge to draw 90-degree lines; use the pivot point and degree scale to mark angles; refer to the molded-in conversion tables for common rafter cuts.

Who Should Buy This

Perfect for:

• Rafter layout and carpentry
• Marking wider boards for crosscuts
• General construction and framing
• Contractors working with engineered lumber
• Crews who’ve broken too many aluminum squares

The Made in the USA designation matters to contractors who want tools manufactured to consistent standards. Empire’s been making layout tools long enough to understand what framers actually need.

The Bottom Line

The Empire 12″ Polycast Rafter Square solves real problems — marking wide boards without repositioning and surviving jobsite abuse that bends aluminum squares. At this size, the polymer construction makes more sense than metal. It’s lighter to carry up a ladder and won’t conduct cold to your hands in winter.

The 1-year limited warranty from Empire Level covers manufacturing defects, though the polymer construction should outlast the warranty period with normal use. This isn’t a precision machinist’s tool — it’s a framing square built to take punishment and keep marking true.

Buy it for the durability and 12-inch capacity. The conversion tables and double-sided markings are nice bonuses, but the real value is having a square that works on modern lumber sizes and survives real jobsite conditions.

Frequently Asked Questions

Q: What’s the difference between the Empire 12” Polycast square and their 7-inch version?

The Empire 12” Polycast Rafter Square (Model 396) offers 12 inches of marking capacity for wider boards like 2x12s and engineered lumber, while the 7-inch version (Model 296) is designed for standard lumber. Both use the same durable Polycast® material, but the 12-inch model provides the extra reach needed for modern framing materials.

Q: Will the Empire Polycast square break if dropped from a ladder?

No, the Empire 12” Polycast Rafter Square is specifically designed to withstand heavy-duty jobsite abuse without breaking. The Polycast® heavy-duty polymer material is engineered to bounce rather than bend or shatter like aluminum squares can when dropped.

Q: Can this Empire 12” square be used as a saw guide?

While the Empire 12” Polycast Rafter Square can technically guide a saw, it’s primarily designed for marking and layout work. The polymer construction makes it ideal for drawing square layout lines and finding angles, with molded-in conversion tables for rafter cuts.

Q: What kind of warranty does Empire offer on this square?

The Empire 12” Polycast Rafter Square comes with a 1-year limited warranty from Empire Level. This covers manufacturing defects in the Polycast® material and construction.

Q: Are the measurements easy to read on both sides?

Yes, the Empire 12” square features SAE graduations repeated on both sides for easy visibility. The markings are molded into the Polycast® material so they won’t wear off, and you can read them clearly whether you’re working right-handed or left-handed.

Q: Is this square actually made in the USA?

Yes, the Empire 12” Polycast Rafter Square (Model 396) is manufactured in the USA. Empire Level produces this tool domestically using their proprietary Polycast® polymer material.
