Festool 489570 Screw Clamps, 4-11/16"

The Festool 489570 Screw Clamps are dedicated workholding accessories designed to lock down guide rails and workpieces. They solve the common problem of materials shifting during precision cuts, making them well suited for woodworkers and tradespeople using track systems or dedicated workbenches.

Built from solid steel, these clamps provide durable holding strength for workshop tasks. They feature a 120mm clamping width (equivalent to 4-11/16 inches) and are engineered to slide directly into the bottom groove of Festool guide rails, keeping the upper surface clear of obstructions. They also provide secure attachment directly with the Festool MFT 3 multifunction table.

Because these clamps are designed with a specific 120mm clamping capacity, they are restricted to materials and setups that fit within that range. Additionally, the provided product information does not specify how many clamps are included in the package or mention compatibility with non-Festool track profiles.

Verdict: These solid steel clamps are an essential addition if you regularly secure materials to a Festool MFT 3 table or use matching guide rails. They offer reliable hold-down support for projects requiring up to 120mm of clamping capacity.

A great fit if you:

• Use a Festool MFT 3 table and need dedicated hold-down clamps
• Want to anchor Festool guide rails via their bottom T-slot channel
• Work with materials that fit within a 120mm clamping span

Consider something else if you:

• Need to clamp workpieces thicker than 120mm
• Do not own or use compatible Festool guide rails or MFT tables
