Good condition as shown! The extra mental shield can function as an extension. It can also function as a “sacrificial” cover so you don’t accidentally give blade rash to the original aluminum guide. Fits a Unisaw Fence that is. 3.4 inches wide. 1-3/4 tall on the front/narrow end. About 2 tall on the back/wider end. The aluminum rail of this fence is about 33-1/2 long as shown in the photo. For even more table saw parts!
