Swan Tools Merlin Double Square

MERLIN Layout Square: Three Layout Tools in One Flat, Reliable Design

Ever set up a face frame or cabinet box, then watched your square rock and tilt as you tried to hold a clean reference line? A tool that will not sit flat leaves you second-guessing every mark, and small errors soon add up across the whole build. The MERLIN Layout Square puts that frustration to rest. It lays completely flat in any position and combines a double square, frame square and ruler in one lightweight tool, so your lines stay true from the first mark to the last.

One flat, dependable tool on the bench, less fuss and more accuracy in your layout.

Key Features

• Three tools in one: Combines a double square, frame square and ruler in a single lightweight, flat-profile tool, so you cover face frames, cabinet boxes and joinery without swapping between gear.
• Lay flat design: The only square on the market that lays completely flat in any position, making it ideal for inside and outside layouts, edge referencing and ruler-style measurements.
• Built-in shelf stabiliser tab: Adds stability and control during layout, so you hold consistent reference points across your material.
• Tru-Mark Edge: This proprietary edge places your line with no offset and no guesswork, so you mark accurately without centre-finding tricks or workarounds.
• Dedicated pencil saddle: Holds your pencil steady for consistent line placement on any precision task.
• Expandable platform: The ruler swaps out with the RED TAIL Ruler Set (Pt# R4612AL), so you can customise the tool to suit your work.

Ideal For

• Cabinetmakers building face frames and cabinet boxes.
• Joiners laying out precise, repeatable joinery.
• Woodworkers who need reliable inside and outside layouts.
• Anyone chasing accurate edge referencing and ruler-style measurements in one tool.

A quick tip: let the lay flat design work for you by keeping the square pressed flat against your material before you mark, so your reference stays true every time. Fit your pencil into the dedicated saddle and lean on the Tru-Mark Edge for repeatable lines across every piece. When a job calls for a different scale or length, swap in a RED TAIL ruler so the MERLIN keeps working the way you do.
