Sörbo easy-on, easy-off End Clips are used to secure the rubber within the 3X4 Adjustable squeegee. Made of stainless steel, they will not corrode and get stuck. To insert end clip, fold rubber end back and wedge the clip between the squeegee and the rubber. To release the squeegee rubber or the end clip, hold the squeegee with one hand and pull the rubber out of the squeegee with the other hand. The clip comes out along with the rubber easily with this method. Do not attempt to pull the clip out with your nail. Sörbo designed the Sörbo End Clip in 1986. Review instructional video.
