ZIPBOLT QT13.900KIT Angled Slip Fix Kit for Rake Applications

Good value strong product that enabled secure installation of banister

These are great, and leave the rail absolutely solid. I've used the angled and the straight connectors - I've found the straight connectors much easier to use, these angled ones can be a little tricky, but they're still well worth the effort. Do read the instructions a couple of times, especially about which connector to use at the top and bottom (could see this being unsafe if this isn't followed). The main difficultly I've found is getting the bottom connector to get and stay in place while tightening (it has a tendency to move as you tighten). Highly recommend a second person to help with this connection. We tried a few tricks to hold it in position, but mostly just tried a few times until we got lucky. Even with the tricky connector, I'd still highly recommend these. The stair rail is absolutely solid, we did use glue too, but the rail was solid the instant these are tightened up. Would also recommend trying the holes on offcuts first, it can be a little tricky to get all the holes correct and have the rail exactly where you wanted it. Used a forstner bit for the larger hole, and didn't tighten too hard with a power tool, just manually tightened the last few turns.

First off, the instructions are rubbish. They miss out a lot of crucial bits and in my case the angle at which the staircase is can be critical in whether this even works to begin with. Mine was a spacesaver with a 62 degree angle and the bottom end was almost impossible to deal with. Also it says not to cut your handrail before you drill in - well I had already cut my rail and you would have to cut both ends to even start the job, I don't see how you can approach this without having cut it first. It says to make adjustments to the handrail cut after, which is crazy. I managed to make the required holes without issue having already cut the rail, you just need to use your noggin when drilling and use a proper timber drill with a point for accuracy. Having an already cut rail will also mess with some of the measurements, but again it's not hard to compensate. So I would approach this with a whole lot of common sense before you go tearing off and following the instructions. The finished result is good, just take your time.

used for securing a handrail to top and bottom newel posts. The instructions are a little complicated and you have to measure your angles etc with care but having said that the instructions supplied are detailed and accurate if you follow them to the letter. Once in place and tensioned the resulting installation is very secure and invisible. The beauty of this fixing is that if required to do so in the future it can be easily disassembled with only minor damage to the underside of the handrail.

The bottom joint worked fine. The problem I had was the top joint as getting the end with the shoulder to engage in the keyhole slot took over twice as long as all the other measuring, cutting and drilling put together. Each time I thought it had engaged and tightened the special (very clever) nut the thing had not engaged after all. As another reviewer noted, the end was too loose and the bolt also rotates compounding the problem. I did follow the instructions to the letter and everything was drilled correctly so a Plan B was required. I drilled another 25mm hole into the underside of the rail at the top end, approximately 25mm further away from the end than the first 25mm hole. This allowed me to access the end of the bolt and fiddle with it until it had engaged in the keyhole BEFORE inserting the special nut. End result is good and strong and worth 4 stars but the pain of fitting it in my case means 3 is all I can give. I would also recommend using a right-angle driver attachment with the hex driver bit. Trying to do it with a standard Hex key will drive you crazy.

Nice and simple instructions, easy to follow, make sure you have the right tools. Did the job perfectly and leaves a tight solid joint.

This is the worst product I have ever bought. First one did not tighten and got stuck inside the handrail and had to be cut out. I gave it the benefit of the doubt and tried the other end which did not get stuck but did not tighten at all. I fixed both ends of my handrail an alternative way. This product wasted my money and my time. If you are considering buying... don't.

Good quality, comprehensive instructions, easy to fit, makes a strong join of handrails to newels

Fairly easy to install. Bottom one goes on first, top one second, they are different. Top one is like a slip-on hook, watch their video first. Only thing was it took 3 weeks to get them from England to Canada, I couldn't find this type for the stairs anywhere. Only type here were for to connect a horizontal handrail, both ends were the same. No glue involved and can be disassembled later if needed. I did not put a plug in the drill hole under each end of the handrail.

Ha llegado muy grata sorpresa al venir de Inglaterra

Absolute trash. Followed directions to the letter and the product broke during installation. I’m left with a major problem as a result. Do not buy.

Product arrived on time performed as expected

I had to adapt the installation instructions to my ramp which was not as thick but it did fit at the end.
