Review: I have spent hours and hours researching deck spacing clips trying to find something in the 1/8 inch spacing instead of the 1/4 inch spacing for Deckorator composite decking boards. The vast majority of the clips are 1/4 inch with screws that show between the boards. I tried one brand that advertised a 3/32 inch space, but the clips were too wide when fitting into the grooves of the boards and did not allow the proper gapping. So I tried this FRUH German design and it worked perfectly. The 1/8 inch gapping is a much nicer look and the screws do not show between the boards. Plus, the stainless steel will out live the plastic competitors by many years.
Review: Worked perfectly for installing composite deck boards, much higher quality than the plastic ones offered at the hardware store.

### ⭐⭐⭐⭐⭐ Review
*by F***N on 11 August 2023*

I spent hours researching and ordering like ten different hidden fasteners, because I didn't like the Trex hidden fastener, the gap was too large between the planks (3/16" to 1/4"). So I tried out all the ones I bought and this Fruh one is hands down the best, sturdy, solid construction, easy to install, and the gap is half the size, about 1/8" (between 3-4mm) which looks so much nicer on my deck. No worries of kids fingers getting stuck or high heels tripping because of the gap. Water can still go down easily and the deck can breathe so mold won't grow (if there is no gap, then that could happen). I saved you a lot of time, trust me, if you are looking for a smaller gap than Trex, you found your fastener. Remember to choose the taller one for Trex, 8.5mm high fits the grooved edge perfectly.
