HidFast Decker Tool Joist Attachment Tool
What it is
- It’s a joist attachment designed to screw onto the back of a HIDfast decking tool (the deck board installation gun).
- Its purpose is to register the fastener height off the joist surface, not from the top of the decking board. This helps set the fastener at exactly the right height to match groove depths on grooved boards (common with composite and hardwood decking).
How it helps
- Precise alignment: By adjusting the attachment up/down, you can fire fasteners so the spur or peg lines up perfectly with the groove on the next board — making installation smoother and easier.
- Better engagement: Especially useful with dense composites or hardwoods, where getting the next board to hook onto the fastener spur can otherwise be difficult.
- Fine adjustment: It works with most grooved boards and allows for very fine incremental adjustment to get the height just right.
About this product...
The Joist Attachment is to be used with pre-grooved decking. The Attachment can adjust to work with almost any pre-grooved board. The Attachment can adjust in very fine increments. The attachment mounts to the back of the HIDfast tool and registers the level of the fastener precisely off the joist surface rather than the top of the decking. By adjusting the attachment up or down, you can fire fasteners with the spur at the precise height off the joists to match the groove height on the deck boards. This saves time when installing dense composite decking and hardwoods.
