Radius Blocks
For use with Exactol Models 412/424 benders.
The412and424bender radiusblockshavebuilt in tubeclamps,
therefore separate clamp blocks are not required. The radius
blocks are interchangeable within bender size ranges. Close
bend radius blocks utilize the small bend radii, but also allow
the bend to begin closer to the end connection.
