Superseding the original AF9 Pro Stubby, the AF9 Stubby MKII is a high quality, CNC machined site protractor with lots of useful features. The AF9 MKII is engineered using 6mm aluminium and anodised in our stylish brand colours for extra durability.
The scales are now lasered directly onto the lower tool arm to improve longevity and accuracy.
The Quad Display Design has 4 scales; protractor angle, mitre angle, butt joint angle and a rise and run. The 'stubby' upper arm is shorter for those hard to reach places and has windows with recessed, precision, red enamel painted arrows. This makes it much easier for the eye to concentrate only on the measurements you need whilst obscuring those you don't.
The protractor window displays the angle between the two arms and is used to measure inside and outside corners or angles between two planes.
The mitre ands single cut windows display the angle needed to cut the mitre/single. This angle can be put directly into a mitre saw. There is a second scale that appears after 45° and this is for use with a pre-cut 45° block to allow more acute cuts on mitre or table saws.
A dedicated handy online calculator for smart phones allows the user to input the protractor reading and instantly get the calculated angle they require for more complex projects. Includes a 3 year manufacturer's warranty.
Suitable for roofing, drywall installs, carpentry, finish trimming, metal fabrication, framing, floor laying, marking and laying out, the applications are endless!
