The Clamex S-20 is a two-part Lamello System connector designed for use with any biscuit joiner. This innovative knock-down connector lets you build, assemble, and disassemble projects with ease — perfect for flat-pack and modular furniture that needs to be moved or reconfigured. The Clamex S-20 is ideal for professional woodworkers who want a strong, versatile, and time-saving joining system.

The S-20 is the same size as the original #20 biscuit, so it fits in any standard 4mm biscuit groove. Because it’s detachable, furniture and cabinetry can be knocked down for transport without compromising joint integrity. It can even be used in material edges as thin as 8mm, making it ideal for built-in cupboards, open shelving, and HPL countertops.

Unlike conventional joinery, the Clamex S-20 requires no glue. Each half of the connector is anchored with two specially manufactured Clamex S-20 screws, then locked together using the Clamex Installation Tool (sold separately) or a 4mm Allen key through a discreet 6mm access hole. This leaves the connection nearly invisible! Despite its minimal footprint, the S-20 delivers a clamping force up to 136 lbs., creating a solid, professional-grade joint every time.

The Clamex S-20 Drilling Jig (sold separately) helps you create access holes at angles from 30° to 180° in materials as thin as 14mm. That makes it easy to produce precise miter joints for wine racks, bookshelves, and other angled assemblies, as well as butt joints in panels as thin as 16mm.

Installation Instructions

1. Cut grooves in your workpieces with any biscuit joiner equipped with a 4mm cutter.
2. Insert the Clamex S-20 Drilling Jig (sold separately) into the surface groove to drill a 6mm access hole.
3. Use the alignment jig to insert the top half of the connector into the surface groove.
4. Lightly tap it with a hammer to make sure it's snug in place.
5. Fasten the connector with two screws, one on each side. Insert the bottom half of the connector into the other groove and repeat this process.
6. Join the two workpieces so that the top and bottom connectors match up. Tighten them with the Clamex Installation Tool (sold separately) or a 4mm Allen key via the access hole.
   

Clamex S-20 is also available in a starter set that includes all the accessories needed for  quick and easy installation.
