About this product
The cursors on the K & E duplex slide rules from the 40s and 50s tend to deteriorate over time, making the rules unusable. This Slide Rule Cursor Frame Replacement Kit allows you to replace your cursor frames with long lasting resin. This kit include everything necessary to replace your deteriorated cursor blocks. As shown in the pictures, this includes the following:
- 2 cursor frame blocks
- 1 cursor spring
- 4 bolt and nut sets
- 1 Allen wrench, for the bolts
IMPORTANT
This set is for the 20" slide rules, NOT the 10" slide rules. The 20" slide rules are thicker, and therefore the frame blocks must be thicker. For the 10" slide rules please see my other listing.
