Wear Gage Blocks
Wear block are "throw away" blocks whose purpose is to prevent wear on the other blocks in
 a set.  Webber Wear blocks are made from croblox® (chrome-carbide) material to provide
 better wear resistance and longer life.

Wear blocks are used at both ends of combinations.  The desired length of the combination
 must include the length of the Wear blocks.  The "wear" side should always be on the
 outside of the combination.  This is the side that is to take any punishment or wear during
 use. 

The other side of the Wear block should always be kept in as good of condition as possible.
 Inspect the non-wear side of the gage block before using it in a combination.  The non-wear
 side is to be wrung to the other gage blocks and should not itself scratch any of the blocks
 it is supposed to protect.
When Wear blocks are sufficiently worn and scratched, they may be discarded and
 replaced at a fraction of the cost that would be necessary if regular gage blocks had to be
 replaced.
Construction:

Wear blocks are identical to other gage blocks except for the following:
     1. "Wear" is etched on the block instead of the Webber brand name.
     2. Wear blocks are only manufactured as B89.1.9 Grade 0, (Webber A1).
     3. Webber Wear blocks are only made from croblox® (chrome-carbide) material.
