This Mod-eezⓇ is a great product for hidden joints in all substrate

Kevin Massie, Blue Fox Carpentry

This plastic dowel is great, it allows me to make strong connections in melamine without the need of clamping

Ruben Moreno, Deferichs

The Mod-eezⓇ System fit together really nice and I expect to use them again.

Blaise Gaston, Blaise Gaston, Inc

I ordered the TUCK dowels and the Knapp plastic dowels. The TUCK metal dowel is by far stronger than the plastic one, but both work for the intended purpose.

The Mod-eez® System

Mod-eez®️ System is a comprehensive cabinet connector that is specifically designed with RTA and knock-down cabinets in mind. This innovative system was developed to tighten joints securely together in a fast and simple method with no visibility of the connector. The Mod-eez®️ uses a spring steel declining ramp, called a “clip” and a large collared shoulder screw at the two mating members. This comprehensive system used to attach the entirety of the cabinet, from start to finish.

Double Clips

Mod-eez®️ Double Clips are used in combination with 2 Shoulder Screws and used for wider dimension board material. They are anti-rotating and can be attached in all wood materials, including metal. Mod-eez®️ clips are made for material as little as 5/8″ in thickness and are ideal for attaching screw strips, countertop strips, toe kicks, and any material greater than 3″ in width. Spring steel clips make the joint strong, yet flexible, while the collar on the shoulder screw adds tremendous resistance to torsional pull-out. Simply slide the shoulder screw head down the ramp of the clips and all fasteners disappear.

The KNAPP®-Dowel is a strong and durable plastic cabinet connector available in 6×28 mm and 8×36 mm. We make our dowels out of the best high-strength weather-resistant (POM) plastic, which gives extra durability in outdoor weather conditions. The threaded ribs are designed to tightly grip into the borehole, therefore, no clamping is necessary. Unlike conventional wooden dowels, the KNAPP®️ Dowel can be used with or without adhesive. If used with the recommended KNAPP®-Adhesive PU+ (Z011/1), the lengthwise grooves and two holes ensure an optimal distribution of the glue and a firm anchoring in the material, hence, creating a strong and tight connection between the components when hardened. Processing can be done is as little as 7-10 minutes after insertion when using KNAPP-Adhesive PU+.

TUCK Spring Steel Compression Dowel

The TUCK is a spring steel compression dowel for attaching cabinet components without glue or clamps that is immediately load-bearing. TUCK is available in five sizes. The 6 x 25 mm, 8 x 35 mm and 10 x 32 mm dowels are processed like conventional wooden dowels. The 10 x 28 mm and 10 x 16 mm are screwed onto a component, while the other end is inserted into a borehole. The spring steel design guarantees permanent tightening by pushing against the borehole wall. The processing can be done with a dowel-boring machine or CNC. Due to eliminating usual clamping aids, the productivity of the gluing of workpieces can also be drastically increased, even in smaller cabinet manufacturers.

QUICK-SET 2-Part Locking Dowel

The QUICK-SET cabinet fastener is a simple and efficient 2-part Locking Dowel connector that includes a threaded stud and a plastic sleeve. It is self-tightening, non-visible, and can be inserted immediately into standard boreholes without the need for glue. Kitchen and bathroom cabinets can be put together on-site quickly and easily, thus high transport costs are omitted. Because glue drying time is not a factor, as a result, the processing of the QUICK-SET connector is the same as with a conventional dowel but in a much shorter time. In addition to its main area of application as a modern cabinet box connector, the QUICK-SET can also be used for drawer boxes, bookcases, closet systems and more.

Biscuit Connectors

Slide-in Connectors

The CHAMP, SUNNY, SILVER and METAL biscuits follow the same design, principles, and functions with slight variations. All of them sit in a standard #20 biscuit slot (4 mm), they are self-tightening, and non-visible. The connector halves are simply knocked into the biscuit slot with a hammer following the radius of the cut. All of the biscuits can also be disassembled, with the exception of the SUNNY biscuit that locks in place. SILVER and METAL have optional integrated locking tabs that can be engaged using a nail punch. These biscuits connectors consist of two identical halves that are installed into the biscuit cut and simply engage by sliding the two halves together.

Clip-in Connectors

FAST is a snap-in cabinet connector that is commonly used for face frame assembly and is also knocked in a #20 biscuit slot. The CLIPS require a #10 biscuit slot and are used to attach toe kicks and removable panels. Both, the CLIPS and the CHAMP are installed using KNAPP Adhesive PU+ (Z011/1). Through the holes on the bottom of the connector, the KNAPP Adhesive PU+ can bond firmly to the material. A permanent connection can be made by gluing the joint.

With 6 different designs, you can join components without the use of clamps or glue for a variety of applications. Whether you manufacture or design kitchen and bathroom cabinets, case goods, closets, or architectural millwork, we have a solution that will work for you.

DUO Hook Connector

The DUO 30 and DUO 35 Hook Connectors are 30 and 35 mm round and consist of two identical shaped steel brackets that hook into each other in a dovetail-like manner. These cabinet fasteners form a stable load-bearing connection immediately after screwing and hooking together the parts. Cabinet end panels and cabinet boxes are simply installed and attached without any visible screws, inside or out.

The KNAPP® Forstner Bit includes a custom adjustable depth stop and allows you to make precise holes on-site. The DUO bracket fits perfectly into the ∅ 30 mm x 3 mm recess. Utilizing the DUO Center Punch, you can mark the wall and/or counterpart at the exact spot where the connection is to be made. KNAPP provides all of the accessories needed to cut down on labor time, giving you an astonishing end result with no visible fasteners.

UNO 30 Hook Connector

The UNO 30 Hook Connector set consists of a round 30 mm Ø stainless steel bracket with a V-shaped receiver socket that is installed with three 3×13 mm Pan Head Screws. A 5×50 mm CS-screw and washer are used as the counterpart. Fast and easy assembly of cabinet to wall and panel-to-wall connections is guaranteed, as the generously V-shaped receiver socket receives the CS-screw head when mounted. Optionally, a spring steel Locking Clip can be added to permanently latch the connector.

The bracket fits perfectly into a ∅ 30 mm x 7 mm recess using our KNAPP® Forstner Bit. The drill bit has an adjustable depth stop which allows cutting the perfect depth every time. Utilizing the UNO 30 Center Punch, you can mark the wall and/or counterpart at the exact spot where the CS-screw goes. The CS-screw is screwed into the component, while the washer is there to set it to the right depth to fit perfectly in the bracket. As a result, this provides the ability to adjust in and out in order to compensate any differences in dimensions.

KLICK System

The KLICK snap-in connector is a double dovetail connector that sits in both sides of a dovetail-shaped groove that is routed in both joining components. The KLICKpro is a connector that has an integrated dovetail and serves as an adapter for the KLICK and sKLICK. The sKLICK is simply screwed in on one component and snapped into the other. Our patented dovetail design for the KLICK and sKLICK is cut with our custom KLICK Dovetail Router Bit, available with a 1/4″, 1/2″ and 8 mm shank. The KLICK-System is one of our most versatile and popular connectors amongst woodworkers and architectural millworkers, and is widely used for cabinet trims, picture frame moldings, face frames, and light rails.
