1、Aluminum Alloy: The parallel guide rail is made of premium aluminum alloy material, with high hardness and good durability. The parallel guide rail has a smooth surface, is not easy to bend or break, and can be used with confidence.2、Easy Adjustment: The limiter and guide rail of the parallel rail can be adjusted. The rail section can be connected to form the maximum rail. The stop of the parallel rail is adjustable. First loosen the large screw and then the small screw to adjust the limit block left and right.3、High in Accuracy: This aluminum alloy parallel rail adopts a splicing type rail slide, with a large screw contact area. The wrench can pass through the screw to estimate the position, and the rail will not protrude during operation. The scale on the tool are clear and the measured values are easy to read, adding more convenience for reading and work.4、Wide Application: Aluminum parallel guide rails guide wood during sawing and securely and easily wrap and quickly clamp onto the guide rails on planers, forming machines, table saws, or log pickers to achieve safe and high accuracy cutting.5、Reasonable Design: The back plate is smooth without jamming to improve your work efficiency, and the locking design can fix the slicing distance with one key to reduce operation errors.
