Keson PG tapes are built to last. The nylon-coated, anti-glare yellow blade provides extended blade life. Blade width is standard 1 inch. The true-zero, 3-riveted hook offers superior strength, and the "bumper" blade return cushions the impact of the hook upon return. The chrome-plated tape armor, positive blade lock and reverse button are standard. All have a handy belt clip. Tapes are printed with 16-inch center and 19.3-inch rafter markings. All 18-series tapes feature continuous inches.
