This spacer is used with our Back Pack® guides to help provide a quieter operation. The No.2826 (1/8") spacer is inserted between the single carrier and its attached Back Pack® Guide.  The No. 2827-A (7/16") spacer is inserted on the other side of the Back Pack® Guide as well as between the master carrier and the adjoining single carrier.

2827-A is used with Model 283-N and Model 283-R tracks and has a 5/8" hole for use with the larger Model 2830 operating cord.
