Significant Services Johnson Level Tool 1956-1800 Metric Johnny Square Professional Easy-Read... Brand: Johnson Color: Black Item Weight: 7.70 Material: Aluminum DESCRIPTION To develop one of the world's best rafter squares, Johnson first had to engineer the EZ-Read finish, its revolutionary anti-glare protective coating that diffracts sunlight rather than reflecting it, so it looks as crisp in full sun as it does in the shade. The EZ-Read finish also increases friction to better secure your square against your lumber when using it as a saw guide. The Johnny Square is highly durable and accurate. Its solid aluminum body construction with CNC machined edges ensure an accurate reading every time. This rafter square also features continuous scribing notches from 2cm to 12cm as well as handy markers that measure 2x4 board dimensions of 1-1/2", 3" and 3-1/2". SQUARE LAYOUT TOOL: Made of extruded aluminum; this triangle carpenter square is CNC machined for durability. This laser-etched square comes with Johnson's best-in-class limited lifetime warranty as it can resist any worksite damage. EZ-READ FINISH: The glare-resistant EZ-Read anodizing method used for finishing this 4 1/2" finish square allows the EZ Read laser etched graduations and numbers to stand out and makes them highly visible. APPLICATION RANGE: The builders and contractor appreciate the versatility of this measuring tool. This square is great for finishing construction; establishing saw blade angles; and more in small spaces. CONTINUOUS SCRIBING NOTCHES: The rafter square has continuous scribing notches for ripping lumber from 1-1/2" to 3-1/2"; as well as convenient markings that measure 24 board dimensions of 1-1/2" and 3-1/2". PRODUCT DESCRIPTION: This black Johnny Square measures 0.75 6.25 3.25 inches and has an erasable space on the back to write finish notes.
