Garbolino presents its Multigrip Open 90 Degree Support as an intelligent and secure alternative to your standard box seat arms. Using Garbolino's signature Multigrip system, the rigid 90 degree angle support clamps and tightens to the seatbox leg instead of sliding up the leg. This makes it far easier to swap and attach your feeder arms, trays, and other seatbox accessories as you please while sat at the bank.The open support grip can be used on 25mm legs, and also 36mm legs by removing the insert.
