New, sealed package For quick, accurate marking of dovetails With riding ledges on both sides, these 2" × 2" markers can be flipped over to mark both slopes of the dovetail Made from anodized aluminum, these markers are light, durable and never soil your work. 1:4 ratio, for those who prefer this angle when working in thinner stock, as it not only provides stronger material interlock than traditional ratio angles but produces a slightly exaggerated dovetail joint that many find attractive. Made in Canada
