These crush (score) slitters are robust and affordable. Made of durable, die-cast metal and quality materials, Precision Lock knifeholders are suitable for typical crush (score) slitting in narrow web applications. The most affordable slitting system on the market, this knifeholder has indexing that assures precise, repeatable placement with 1 mm (0.04 inch) spaced increments, and the potential wobble of a tilted knifeholder is reduced significantly because of the true vertical alignment of the indexing rack. Set-up, installation and adjustments are a snap using a simple, effective toggle quick clamp.
