Invisible joinery. Swiss precision. No clamps.

A joinery system built around one T-shaped profile groove cut by the Zeta P2 biscuit joiner (or a CNC with the P-System cutter). Every P-System connector — Clamex, Tenso, Bisco, Divario — pushes into that groove by hand and locks in the undercut, so joints are form-locking, strong across the whole face, removable without wear, and need no glue, screws or clamps to hold. The connectors sit inside the panel, so the finished joint shows nothing but, on Clamex, a 6 mm access hole.

The Zeta P2 (carbide or diamond cutter) and Zeta P2 Cordless, Clamex P-14, P-10, P-14/10 Medius and P-14/10 Flexus, Tenso P-14 and P-10 with pre-load clips, Bisco P-14 and P-10, Divario P-18, the Basic and Professional connector assortments, Divario starter sets, replacement carbide and diamond cutters, the Divario marking jig and installation tool, and the Clamex flexible fitting tool. Everything else in the Lamello USA catalog — Classic X, Top 21, Cabineo, Invis, biscuits, CNC tooling — is available special order.

Prices on this page are Lamello USA minimum advertised pricing effective September 2026: the Zeta P2 with carbide cutter and drill jig is $2,000, with the diamond cutter $2,175, the Zeta P2 Cordless kit with two batteries and charger is $2,650 (bare tool $2,250). Clamex P-14 and P-10 are $175 per 80 pairs, Tenso P-14 $105 per 80 pairs. Cabinet shops and installers can request a quote for volume pricing.

Clamex is a detachable cam-lock connector: insert both halves, lock with a hex key through a 6 mm hole, and the joint can be taken apart later. Tenso is a self-clamping connector used as a gluing aid: it pulls the joint closed and holds it while glue cures, so no clamps or presses are needed, but it is permanent once glued. Use Clamex where parts must come apart (removable face frames, knock-down casework, finishing after dry assembly) and Tenso where you would otherwise clamp a glue joint (attaching face frames, fillers, scribes, miters, drawer boxes). Both use the same Zeta groove.

The number is the installation depth in millimetres and the Zeta P2 depth setting. P-14 connectors (Clamex P-14, Tenso P-14, Bisco P-14) need material at least 15–16 mm (5/8") thick and are the standard for 3/4" cabinet stock. P-10 connectors are shallower for 12–13 mm (1/2") material and for miters from 15 mm — drawer boxes, thin backs and crown molding. Medius and Flexus combine a 14 mm half with a 10 mm half so two shelves can meet a single 16 mm dividing panel.

The carbide-tipped cutter (101403S / 132141) is recommended for dense hardwoods and can be re-sharpened — Family Hardware sharpens it in our own carbide sharpening shop. The diamond-tipped cutter (101403DS / 132140) lasts far longer in abrasive sheet goods such as MDF, particleboard and plywood but cannot be sharpened. Shops running mostly plywood and melamine usually choose diamond; solid-wood and mixed shops often keep one of each.

Yes. Turn the P-System depth adjuster to OFF to disable the vertical mechanical drive and fit the optional 4 mm blade (art. 132000, special order) and the Zeta P2 cuts standard slots for original Lamello wooden biscuits (#0, #10, #20). Many shops keep the Zeta on P-System duty and run a Classic X or Top 21 for wooden biscuits.
