P1 Mini Centre-Loc Adjustable Back Rest The Solar P1 Center-Loc Adjustable Back Rest is the ultimate backrest. A world-first in design, the width of the arms on this backrest can be adjusted to perfectly suit any rod butt from thin carbon blanks to Duplon handles via an adjustment system cleverly housed inside the central screw thread. Simply loosen the bolt inside the screw thread using the supplied allen key, set the backrest to the size you need and then lock the arms in place by tightening the bolt. The result is a versatile, streamlined backrest that will provide a lifetime of service. The Flexi-Grip arms are designed with a small amount of inherent flex and feature rubberised grips for a secure grip on any rod butt. The precision-machined, 5-Spoke Diamond-Grip body matches the rest of the Solar P1 range and are made in the UK entirely from top quality stainless steel. The 3/8″ BSF screw fitting means that these are universally compatible; they will fit with almost all banksticks and buzz bars. Available in Small (for abbreviated or shrink wrap butts) or Large (for Duplon or Cork handles)
