Clip-Locking Turnbuckles utilize 2 locking clips instead of lock-wire for safety. The turnbuckle barrel and terminals are slotted lengthwise to accommodate the locking clips. After the proper cable tension is reached the barrel slots are aligned with the terminal slots and the clips are inserted. The curved ends of the locking clips expand and latch in the vertical slot in the center of the barrel. Build up MS turnbuckle as sem blies, similar to the AN assemblies listed on the preceding page, by selecting a turnbuckle barrel, 2 end fittings and 2 clips from the components listed in the Table below. The price of the complete as sem bly is the sum of the prices shown for the components.

Example: An MS turnbuckle assembly for 3/32" dia. cable, with fork end and pin eye consists of:
    1 MS21251-B3S Barrel
    1 MS21252-3LS Fork End
    1 MS21254-3RS Pin Eye End
    2 MS21256-1 Clips
Less 10% for 6 or more complete assemblies.
Less 15% for 12 or more complete assemblies.

Note: MS21256-1 clips are short (1") and MS21256-2 are long (2").

Q: I am ordering 6 turnbuckle barrels P/N: MS 21251-B5S. My questions are:<br> 1 - Does this barrel take the clips? <br> 2 - If it does take the clips - Which clips, since you have 2 part numbers listed?

Yes, the MS21251-B5S uses the clips. The S at the end of the part number indicates it is a short barrel, so you would need the MS21256-1 clips.
