Scotchman® Measuring Systems are manufactured from the highest quality stainless steel investment castings. The systems can be adapted to almost any type of metal or wood machinery. Both the multi loc and quick loc systems are designed to give you quick, easy and accurate length setting. With the quick loc system, you simply move the stop on the rail to your desired length. The multi loc allows you to put several stop blocks on one rail for multiple settings. Simply move your material from one stop to the next. This patented design eliminates any tightening of nuts, bolts or locking devices. Simply set the stop at your desired length and the stop will automatically lock in place for a guaranteed accurate length setting without any stop movement.
