This kit is designed to upgrade the crown guard facility on older circular saws that commonly have either a simple ineffective set-up or even no crown guard at all! It is easy to adjust to fit almost any medium-sized circular saw, including those fitted with a side support table. With a set of height adjustable feet, telescopic arm and lower support, there is plenty of adjustment. The clear Perspex hood is wide enough to allow for blade tilt and has a parallel system to keep the hood lowered over the blade. The kit also provides for extraction from above the blade, leading to a 100mm port at the end of the arm. A simple bracket enables the kit to be bolted to the saw; just two holes need to be drilled into the machine's casing. The top arm can also be swivelled away from the blade to allow blade changing. To check whether this kit would suit your saw, the top arm reach is 1,000-1,700mm. Lower support arm adjusts from 1,080-1,280mm. Suits table heights from 900-1,050mm. Suggested max blade size, 305mm with a scoring blade, 355mm without.
