The Summit Adjustable Colosseum Black Edition Buzz Bar is a UK-manufactured buzz bar combining high grade aluminium and stainless steel for a lighter yet durable option than a full stainless steel design. It is fully adjustable, with an engineered inner mechanism that prevents twisting and keeps the buzz bar solid once set. The ergonomic thumb screw lets you extend and retract the bar easily, whether you want all rods tight to one spot or spread out across a wider area. The thumb screws can be tightened by hand or with the easy-tight key accessory, which is useful in wet weather conditions.
