Sturdy Railing
Follow the instructions and it will work!Pro Tip: cut a 2x4 to fit where the upper rail goes and use as a template before cutting the expensive hardwood handrail.

Works as advertised.
Hold tight. I have had issue with these things binding up but I spray the nut side when a little dry silicone and I can assemble and reassemble on site without worrying about getting stuck.Installation is simple enough. If you think you can install a handrail you should be able to follow the directions on the package.

Great Hidden Fastener!
These work as advertized. I recommend ordering the ZipBolt Railbolt Drill Guide which helps mark the 1" hole on bottom of the rail. It also is a life saver when drilling the 3/8" hole in the end of the rail. I opted to clamp the drill guide to the bottom of the rail so it wouldn't move when drilling. I found that there is a little bit of wiggle room if all the drilled holes and the parts aren't perfectly square. When installing the gear in the 1" hole, hold it in place with the hex bit against the the side of the hole where the bolt comes in, then slide the bolt into the 3/8" hole and screw the bolt counter clockwise into the gear so it sticks out of the end about a 1/4". Then slide the gear so the bolt is flush with the end of the rail. Then put all of the balusters in the holes in the rail, stand it up in place, line up and extend both bolts into the key hole plate in the post and push everything down. Tighten the bolts with the hex bolt bit turning clockwise. I have big strong hands so I tightened all the connections by hand. I am an experienced carpenter and it still took a fair amount of time, but the finished product was worth it.

Don’t Buy!!!
Didn’t work. The mechanism would break every time. Pieces of junk.. better off screwing it in.

Don’t know how I would’ve finished my railing without these
I had never used these or anything like them before, but was able to make a very nice stair railing with them. I honestly don’t know what I would’ve done without these. They are fairly easy to use and make for a very sturdy railing. I would definitely use these again if I ever needed to do another railing.

Follow the instructions to a T and these are AMAZING!
This is not for the Joe Blow homeowner to install… the negative reviews including the first video are from not understanding how the product works.The bolt has a hex pattern on the head that locks into the slot in the keyway to keep it from spinning… on the four I installed, finger pressure was enough to hold it in place while I tightened it enough to retract it to install.Use high quality Freud or similar Forstner bits, drill your holes perfectly square and this product will make you a believer.10/10 would recommend if you’re a competent woodworker or carpenter. Leave it to a professional if you’re not a super handy person.
