Ejecting Blades

Ejecting blades provide a simple and reliable means of stud ejection. The ejected stud is retained in proper alignment for locking, yet completely clears both support and panel holes.


For Size 3 Studs:

There are two styles of Ejecting Blades for the Size 3 Studs. The 1224-159, 1224-159-1 and 1224-1031-1 Ejecting Blades require a retainer to hold the stud. The 1224-721 Ejecting Blade has a split in the end with the hole smaller than the stud end. This allows the Ejecting Blade to clip over the undercut of the stud and to act as the stud retainer.

The 1224-159, 1224-159-1, 1224-1031, 1224-1031-1, and 1224-721 Ejecting Blades add .015 in. (0.38 mm) to the total pileup calculation.
