The TurnLock concept turns changing guide bushings and installing router attachments into a simple matter of a 1/4 twist - no tools needed. Align the TurnLock bushing inside the TurnLock base and twist. The cogs on the outside of the bushing slip into the slots on the inside of the base, locking the bushing in place. Base plate is made from clear resin that increases visibility of the work area and allows for more consistent alignment of router bits with any template shape. Special ride pads keep router base scratch free. TurnLock base attaches to any of the Milescraft router attachments. Set contains 7" universal TurnLock base plate that fits most routers up to 3 HP (horsepower), centering pin, top hat adaptor that converts non-TurnLock metal bushings into TurnLock Quick Change Bushings, and 8 bushings (5/16", 3/8", 7/16", 1/2", 5/8", 51/64", 7/16", 5/8" extended nose). Detailed instructions included. No. 1201: Base Length: 9.5" ---- 1. 海外直輸入品となりますので、新品であっても、パッケージに多少のダメージがある場合もございますが、商品本体には問題ございませんのでご安心ください。2. 日本国内でのメーカーによる製品保証等は適用されません。3. パッケージや、説明書等は、英語表記となります。
