Keep your deck surface as smooth, clear, and unblemished as the day it was built with the durable Mantis Clip hidden fastener system. Mantis Clips directly attach your deck boards to your joists via a groove in the side leaving the tops of your boards clean and untouched while providing a secure hold day in and day out. Mantis Deck Clips automatically space deck boards 3/16 of an inch apart for a consistent look and beautiful appearance throughout your outdoor project.

Crafted from solid powder-coated steel or stainless steel (for coastal applications), Mantis Clips also elevate your deck boards off the joist surface to reduce rot and load stress. No more rising deck nails catching feet or shovels, just a cost-effective fastening system that is completely concealed to let your deck shine.

Mantis Clips work with virtually grooved edge decking by offering 5 different groove heights:
Mantis 320 is designed for boards with a 0.325 inch groove height
Mantis 345 is designed for boards with a 0.353 inch groove height
Mantis 385 is designed for boards with a 0.380 inch groove height
Mantis 396 is designed for boards with a 0.406 inch groove height
Mantis for Trex is designed for boards with a 0.396 inch groove height
