Cabinets H-Clip Construction

“Each fastener that we have carefully designed was created under the same principles: simplify manufacturing, simplify assembly, and simplify installation.”

The H-Clip fastening system consists of three main components; the Barbed H-Clip, Spring Pin, and Router Bit. The system works with panel thickness ranging from 5/8″ to 3/4″ and a variety of different materials: particle board, plywood, hardwood, and selected plastics. The H-Clip system is constructed with spring pins on every joint in a one-to-one ratio. This method provides ever greater rigidity and pull force, and cannot be pulled apart or disassembled. As with all of our connecting solutions, the H-Clip fasteners use no special tools, no glue or clamps, drying or clean up…and are completely invisible after assembly for beautiful aesthetics!

Simplify the Cabinet Building Process

The H-Clip system is designed for lean manufacturing,
improving on key elements to increase production and reduce cost.

The first thing we improve is the fastener; from multiple confusing pieces down to a single piece design utilizing a keyhole slot to create the locking mechanism. This greatly reduces the fastener cost but more importantly, it simplifies the insertion process. Having fasteners on the surface often require manual labor or expensive specialized equipment for installation. Lockdowel only requires the fastener to be inserted on the edge and integrates perfectly with existing proven edge drilling or dowel insertion machines.

To eliminate the glue requirement when constructing a cabinet with no visible fasteners and comparable strength, we designed the interference of the barb geometry and keyhole slot to perfection. Together, each H-Clip joint provides over 100 lbs of pull force and once assembled, no fasteners are visible. Each H-Clip joint also include an 8 mm spring pin to provide over 700 lbs of sheer strength. The wood will break before our fasteners do.

To start, cabinets built with Lockdowel fasteners pass all ANSI/BIFMA or AWI Standard. But we don’t stop there. Our fasteners are engineered for rigorous testing and we will work with you to meet all specialized requirements.

Simplicity in design, the fastener naturally reduce the assembly process. The h-clip snaps on firmly inside the keyhole slot. With practice, a base cabinet can be assembled in 2 minutes, and a drawer box in 30 seconds. Every product we have converted to Lockdowel shows a significant increase in assembly time by as much as 60%.

Step 1: Surface Routing

Any CNC router that is capable of holding 0.10 mm tolerance can use our router bit for milling the key slot routs. An h-clip rout consists of 1 pass at 10.75 mm which creates an undercut for the h-clip to snap into. Next to the h-clip rout is a standard 8 mm hole for the use of spring pin which is essential to the design to provide sheer strengths and squares the cabinet.

Step 2: Edge Machining

We work with equipment manufacturers to integrate our fasteners for automatic insertion with an edge drilling machine, but starting with manual insertion is still faster and easier than before. The barbed h-clip and spring pin use standard 8 mm diameter drilling and 32 mm spacing.

More manufacturers and machinery are available on our equipment page.

Step 3: Assembly

Lockdowel product shares a very similar linear work cell that consists of routing, edge banding, edge drilling/insertion, and assembling the piece. The whole process of construction a cabinet from start to finish is 6 – 10 minutes per cabinet. Time is dependant on the CNC router speed and setup. The easiest step is assembling a Lockdowel product which takes about 2-3 minutes per base cabinet and 30 seconds for a drawer box.

Step 4: Installation

Built in with our cabinets design is the hanging rail system. Level and install the hanging rail to the kitchen wall and hang the cabinets for easy installation.

Simplify the Implementation

Lockdowel has built an extensive library of hundreds of products that had been converted to using Lockdowel’s hardware. We partnered with software developers in the woodworking industry to provide our cabinet product library to you for free.  We also provide support for prototyping, testing, and equipment needs. We have also partnered with premier equipment manufacturers to provide even greater efficiency with automatic Lockdowel fastener insertion machines. Our job is to make your life simple and ensure a smooth and accurate transition when using our products.
