Short Answer
The Diamond Deck bracket clamps to a vertical tube with a C-shaped coupler and clamp screw. Two arms with pockets hold 2x4 toeboards. A pin-and-sleeve pivot runs straight, turns 90 degree corners, or locks at any angle. Set screws hold each board. No wire, nails, or scaffold modification.
The Diamond Deck bracket solves the toeboard installation problem by replacing tie wire, nails, and wood blocking with a steel bracket that clamps to the vertical scaffold tube and holds the boards with an adjustable, lockable pivot. Here is how every part of it works together.
The Coupler: Clamping to the Vertical Tube
The heart of the bracket is a C-shaped coupler that wraps around the vertical scaffold post at deck level. A clamp screw threads through the coupler and tightens it onto the tube, much like a standard scaffold coupler. Once tight, it is designed to stay fixed without shifting.
Made from steel using standard scaffold hardware materials, the coupler is designed for vertical tube scaffold posts. Fit testing on major tube scaffold systems is in progress; confirm compatibility with your specific system before deployment. It attaches to the post, not to the ledgers or planks. One coupler holds two bracket arms extending in opposite directions, giving you the two boards you need to frame a corner or the two sides of a straight run.
The Two Bracket Arms and Toeboard Pockets
From the coupler, two steel arms extend about 6-1/4 inches each. At the end of each arm sits a toeboard pocket sized for a standard 2x4 board (about 2 x 2 x 2 inches). The pocket has a flat base plate, upright retainer plates on two sides, and a top opening where the board slides in.
Once the board is seated, it is designed to sit without wobble or shift. The pocket is rigid and holds wood or metal toeboards equally well. If your site runs thicker lumber than standard, shim material can be used; the pocket is designed for jobsite flexibility.
The Set Screw: Locking the Board Down
A set screw threads through one of the upright retainer plates and clamps the board in place. Hand-tighten it for quick adjustments or wrench-tighten it for a permanent install. Either way, the board is designed not to shift once locked. No wire, no nails. If the board needs to come off for repair or swap, loosen the screw, lift it out, and re-install it.
The Pivot Assembly: Adjusting the Angle
Where the arms meet the coupler sits a pin-and-sleeve pivot assembly. This is similar to a door hinge. The arms pivot up and down around a central axis, and the angle adjusts through at least 180 degrees of travel. This gives you three core configurations in the field:
- Straight run: Both arms extend parallel to each other, holding two boards that run the length of a platform edge.
- 90 degree corner: Swing one arm square to the other, and you hold two boards at a right angle to frame the corner of the deck.
- Any angle in between: The pivot locks at any intermediate angle, so you can handle angled sections or custom orientations without cutting or modifying the scaffold.
Once you set the arms to the angle you want, a locking fastener (typically a pin, set screw, or bolt and nut) holds that angle in place. The arms are designed to hold their angle without drifting.
The coupler also rotates independently of the pivot assembly, giving you a second degree of freedom. You can rotate the entire bracket around the vertical tube to point the arms in a new compass direction, and adjust the arm angle separately. This combination lets you install boards in nearly any configuration without moving the bracket or modifying the scaffold tube.
Installation: The Three-Step Process
Putting the bracket into service is straightforward:
Step 1: Clamp the coupler. Position the bracket at deck level on the vertical tube. Tighten the coupler clamp screw until the bracket is secure to the post. Check that it does not rotate or rock.
Step 2: Set the angle. Swing the arms to your chosen configuration: straight for a run, square for a corner, or any angle in between. Engage the locking fastener to hold the angle in place.
Step 3: Drop in the boards and lock them down. Slide each toeboard into its pocket until it seats flat on the base plate. Hand-tighten or wrench-tighten the set screw on each board until it is snug. The boards are now locked and designed not to shift.
No additional fasteners, no modification to the scaffold tube, no consumables consumed. When the scaffold comes down, the bracket comes off with it and moves to the next job.
What It Is Designed For
The bracket is designed to meet the toeboard requirements of 29 CFR 1926.451(h)(4). Load testing is in progress and Professional Engineer review of the design is in progress. Fit testing across major tube scaffold systems is also in progress. A provisional patent application covering the bracket, its adjustable pivot, and the installation method is on file (U.S. patent pending).
As with any scaffold hardware, confirm that the bracket fits your scaffold system under 1926.451(b)(10) before it goes into service, and have your competent person inspect the final installation.

Frequently Asked Questions
What Is the Main Part of the Diamond Deck Bracket?
A C-shaped coupler with a clamp screw that grips the vertical scaffold tube. The coupler connects to two bracket arms that swivel on a pin-and-sleeve pivot and independently rotate. This gives you straight runs, corners, and any angle in between.
How Do the Arms and Pockets Work?
Each arm extends about 6-1/4 inches from the coupler and ends in a pocket sized for a standard 2x4 toeboard (about 2 x 2 x 2 inches). The pocket has upright retainer plates on each side and a tensioning set screw that locks the board down. Wood or metal boards both fit.
How Do You Set the Angle?
The pin-and-sleeve pivot between the arms and coupler adjusts through at least 180 degrees. Swing the arms to run straight for a long edge, square them for a 90 degree corner, or angle them as needed. A locking fastener holds your chosen angle. The coupler also rotates separately for extra adjustment range.
How Does It Lock the Boards in Place?
Once the boards are seated in the pockets, a set screw through each retainer plate clamps the board down. The screw is hand-tightened or wrench-tightened depending on the fastener type. No consumables like wire or nails needed.
What Scaffold Systems Does It Fit?
Designed for vertical tube scaffold posts. Fit testing on major tube scaffold systems is in progress. Confirm compatibility with your specific system before deployment. See the specifications page or request a quote for fit status.
