Insert blocks are the small hardened-steel slugs that sit inside each saddle and clamp the string end when the lock screw is tightened. When they deform — or when the screw head rounds off — the saddle can no longer grip the string. Tuning stability goes with it. This is a set of six replacement blocks for Floyd Rose Non-Fine Tuner systems, finished in black, part number FRNFTSLIBP.

These blocks are series-specific. Non-Fine Tuner saddles are not the same dimension as Original Series or Fine Tuner saddles, and the wrong block will not seat correctly. Before ordering, confirm your bridge is a Floyd Rose Non-Fine Tuner system. If you are not certain which series you have, measure the saddle or send us the make, model and year of the guitar.

The blocks are hardened steel. That matters because softer material deforms faster under clamping load, and a deformed block loses contact area against the string end. The black finish matches the original hardware. Buy a full set rather than replacing one at a time — if one block has failed, the others have the same mileage on them.
