The Wychwood Solace NTS (No Thumb Screws) Screw Points Banksticks are made from a 16mm Diameter, strong aluminium, complete with screw point. Each stick incorporates a 2BA thread designed for you to screw your bobbins/indicators into. They have our very own ergonomically designed knurling pattern on the height adjustment locking mechanism and also the alignment collars. Each stick has a spike on the internal upright stick, meaning they can be used in hard ground.
