Turnbuckle Body for 4600 lb Loads

The Loos MS21251-B6S turnbuckle body provides a 4600 lb working load limit for tensioning applications. It is built from brass with a 2 1/4 in overall length and 5/16 in UNF threads. The component suits rigging setups that require right-hand and left-hand thread adjustment.

MIL-DTL-8878 Standard and Thread Limits

This turnbuckle meets MIL-DTL-8878 specifications for mechanical performance. The 5/16 in -24 UNF thread size defines the compatible hardware range. The design accepts 3/16 in rope diameter within the stated load limit. Brass construction offers corrosion resistance for the intended service conditions.

Verify Thread Size and Rope Diameter

Confirm that your existing rigging uses 5/16 in -24 UNF threads before ordering. The working load limit of 4600 lb must match or exceed your system requirements. Ensure the 3/16 in rope diameter is compatible with your current lines. Check that right-hand and left-hand thread direction suits your tensioning arrangement.

Questions about this item

Should I pick the 4600 lb working load limit or a different capacity for my rigging?

The turnbuckle body is rated at 4600 lb working load limit and fits 3/16 in rope, so choose it when your load and rope match those figures.

What does the 4600 lb working load limit mean once the turnbuckle is installed?

It means the assembly can safely hold up to 4600 lb under normal straight pull when correctly tensioned and inspected.

Does the 5/16-24 UNF thread cap the load or the adjustment range?

The 5/16-24 UNF right-hand and left-hand threads set the adjustment range; the 4600 lb working load limit caps the load.
