This accessory for the variable angle worktop jig takes the guesswork out of cutting a joint to fit walls that are not quite square. Using a standard jig, overcoming non-square walls is inaccurate and poor joints are often the result. The Angle Adjustment System eliminates this and produces a perfectly matched joint. CNC machined from durable aluminium, it fits into a slot already machined in the jig. Engraved markings on the variable angle worktop jig allow adjustments to change the angle of the male joint. It allows you to achieve accurate joints with internal angles between 85° to 95°. An added advantage of the Variable Angle Worktop Jig is that you can use it to find and set the angle required, resulting in a perfect joint. Full instructions included (UK Patented).
