  • Self-Locking Slide-In Connector for #20 Biscuit Slots. The SUNNY Biscuit Connector installs quickly with a hammer and locks in place without clamps or glue. Integrated tabs engage on assembly to prevent gaps and create a secure, tight joint.

Product Description

SUNNY Biscuit Connector – Quick, Clean, One-Way Assembly

Slide-In Precision for Permanent Joints. SUNNY is a #20 plastic biscuit connector that installs in seconds with just a hammer—no clamps or glue required. The patented cutting edges hold securely, while integrated locking tabs engage automatically for a tight, gap-free joint.

Perfect for Miter Joints, Trim, and Case Goods. Ideal for face frames, shopfitting, and furniture builds, SUNNY is especially effective in mitered corners where precision and speed are critical. It also works as a gluing aid when extra reinforcement is needed.

No Clamping. No Waiting. Just Lock and Go. Once the connector halves are inserted and pushed together, the joint becomes load-bearing immediately. SUNNY’s self-tightening mechanism ensures a clean connection that stays tight over time.

Permanent by Design. SUNNY is designed for strong, one-way connections. Once assembled, the joint cannot be disassembled—making it perfect for flat-pack, modular, and high-strength applications where durability matters.

Works With: softwoods • board materials • RTA furniture • cabinetry • architectural millwork • corner joints

SUNNY – Biscuit Connector - Installation

SUNNY – Biscuit Connector

Biscuit Slot Preparation

Make a standard #20 biscuit slot using a biscuit joiner or CNC. Set the depth to approximately 12.5 mm to match the connector’s profile.

Strategic Connector Placement

  1. Angle the connector tip at the edge of the slot, aligned with the curve.
  2. Push into the slot, ensuring the halves are mirrored for correct alignment.

SUNNY – Biscuit Connector

Efficient Assembly Technique

Tap the SUNNY connector into place with a hammer, following the radius of the slot. The cutting edges will grip the material as they lock into position.

SUNNY – Biscuit Connector

Seamless Integration

  1. Confirm the outer connector edges are flush with the surface.
  2. Press the components together, allowing the locking tabs to engage. This creates a tight, permanent joint.
