Workshop accessory that creates straight, stable joins between guide rails for precise long cuts. Automatic alignment reduces set-up stress and cuts the chance of costly rework. Is Festool Connecting Piece FSV/2 the useful upgrade your workshop needs?

⚡ At a Glance
  • Alignment Accuracy: Automatic self-alignment ensures a straight, square join between guide rails
  • Best for: Woodworkers and installers joining long guide rails for accurate, repeatable cuts
  • Not ideal for: Projects that do not require joining two guide rails together

Two laser-marked joining pieces create a stable connection between two guide rails. Automatic alignment helps achieve a straight joint for accurate long workpieces.


Straight, repeatable joins - with automatic self-alignment

Automatic self-alignment uses matched geometry in the two joining pieces to bring guide rails into register when connected. Laser-engraved marks indicate the correct order for placement to avoid assembly errors.

Consistent, square joints cut down on measuring adjustments and rework, so long boards can be processed faster and with greater confidence.

Stable long-rail connection - thanks to a two-piece joining system

Two separate joining pieces lock the ends of adjacent rails together to create a continuous support line for long workpieces. The design spreads alignment forces across both parts for mechanical stability.

Stable joined rails reduce flex and misalignment during cuts, helping to keep bevels and rip cuts accurate over longer lengths.

Faster, mistake-free setup - with laser-engraved placement guides

Laser engraving marks each joining piece so they are positioned in the intended order and orientation. Clear markers remove guesswork during assembly.

Quick, unambiguous set-up cuts down time on the bench and reduces the chance of crooked rails caused by misordered parts.
