Get the job done faster
Stay in the groove with a spacer that can keep up with your work. The BumpFin spacer moves with you, reducing the number of total spacers required and the time positioning them. Fluted fins reduce friction during slide motion, and a tail-grip ensures easy removal from boards pressed up tight. Top fins on our Lite model offer an overhang gauge for quick alignment without a tape measure. Bumpfin designs are patents pending.

Ergonomic durability

Armored aluminum through holes are countersunk to funnel screws into position. Durable body material is highly visible, heat resistant, and has minimal flex. Chamferred edges and surface features are nice and grippy.

Credit card
Consistent quality

Ensure identical board AND screw spacing across your entire crew regardless of experience, with whatever screws you like. Reduce risk of invalidating your warranty.

Operation

Speed without compromise.

Slide the spacer along with your work

Slide the BumpFin spacer between deck boards till it makes contact with the joist - then you're ready to insert screws. The through holes are at just the right spacing to offer a balance between strength and low profile asthetic. Tip the BumpFin tail up and over the joist to continue sliding into the next position. Bumpfin designs are patents pending.

Let the joist confirm you're in place

The BumpFin comes to a stop when it's in position, and the viewing window proves you're centered over the joist.

Forget the bucket of spacers

You may not need a bucket of spacers and templates anymore. These slide along with your work, serve the function of both, and take up minimal room in your toolbox.
