EM-2 is 1/4-20 tap on any end of a 1/4" slotted extrusion like EX-11, EX-22, etc. or a 5/16-18 tap on any end of a 5/16" slotted extrusion like EX-1, EX-6, EX-2, etc.

EM-3 is a .28 dia or .31 dia clearance hole in the slot of any extrusion

EM-5 is a .56 dia counterbore on any 5/16" slotted extrusion for use with the FRAME-WORLD anchor fastener such as EF-62, EF-63, & EF-64

Please indicate in the order notes what extrusion machining matches up with the extrusion that is being ordered. Also, please order the correct number of machining services necessary.  For instance, if you want both ends of a 3 pieces of EX-6 at 48", then 6 taps are required.  (6) EM-2's should be ordered for this example.  If you are ordering 2 pieces of EX-3 @ 36" and need 1 end tapped on each, then 8 taps are required [8 EM-2's].
