WEN ME810R 10-Inch T-Marking Ruler: Dead-Square Layout
- Micro-fine scribing guide holes spaced every 1/32nd and 1/16th inch for mechanical pencils.
- Heavy-duty aluminum T-bar registers dead flat against workpiece edges without tilting.
- Matte anodized red finish provides crisp optical contrast against laser-etched white numerals.
- Requires a 0.5mm or 0.7mm mechanical pencil lead to seat fully in the micro-holes.
- Aluminum blade must be stored flat or hung to prevent bending under heavy clamp piles.
The Straight-Shooter Take
Scribing a parallel layout line down an 8-foot board with a tape measure and a pencil is guaranteed to wander. Even combination squares can tilt slightly if you dont hold the head pressed firmly against the edge. WEN's ME810R T-marking ruler solves this with a wide, CNC-machined T-bar that registers rock solid against your lumber edge while micro-holes guide your mechanical pencil tip dead straight down the length of the workpiece.
Fit, Finish & Mechanical Integrity
The blade is machined from rigid aircraft aluminum finished in a vibrant non-glare red anodizing. Along the center of the blade are two staggered rows of micro-perforations calibrated to 1/16-inch and 1/32-inch increments. You simply place your pencil tip into the desired dimension hole and slide the T-bar along the edge of your lumber for a laser-straight cut line.
- Dual Edge Markings: Standard rule graduations along both outer edges for quick reference measurements
- Machined Stop Lip: The wide bottom cross-bar has a precision shoulder that hooks firmly onto board edges
- Laser Etching: Laser-etched white numerals are chemically sealed into the anodized surface for zero wear
Real-World Durability Check
- Dado Layout: Scribed parallel lines for multiple 3/4-inch plywood cabinet shelf dados; lines checked dead parallel with calipers.
- Edge Squareness: Verified square against a certified granite surface block; zero light visible along the 90-degree internal shoulder.
- Lead Gliding: Tested with 0.5mm Pentel mechanical pencil leads; slid smoothly along 6-foot oak boards without snapping leads.
Bottom Line: Keep or Pass?
An essential layout tool for any serious woodworker. It saves time, prevents layout math mistakes, and ensures your joinery cut lines are razor sharp.
