6 Pcs 1" Split Square Tube Connector, Stainless Steel 3 Way L Square Tube Fitting Fence Guardrail Rail Clamp

La pieza es fiel a la medida.

The Allen head screws are a good feature but the jam nuts are useless. The screws need to be at least 2mm longer with a NYLOC nut - so that it doesn't fall off. I ordered replacement Nyloc nuts on Amazon to try to fix the problem.

This solved my problem of connecting to 1“ x 1“ pipes with out Welding

Normally I would weld 1" square tubing together but a new project required being able to disconnect certain pieces to add/remove a canopy. These looked like just what I needed so ordered a set. I selected this supplier as I noted in the pictures that the "fingers" on back side mated nice and flat - unfortunately the ones I received don't. They should have nice 90 degree bends but are more like 95ish degrees. This results in the "fingers" interlocking but with some offset exposed that can catch items.A feature I didn't notice the in ad is that one half has a thru-hole for the bolt whereas the other half is threaded. A pleasant surprise that makes the assembly go more easily as you can quickly thread the bolt in to hold the pieces together without having to add the nut. But make sure you don't dump all the pieces into one pile as you'll be searching for the mating pieces!The supplied nut/bolt are fine for most applications and the bolt length avoids excess threads exposed beyond the nut. However in my application there will be significant vibration so I opted for a longer bolt with flange head and flanged nylon locking nut.Final note is that the bolt hole is set back just enough that you can insert the 1" tubing up against the other piece, drill a hole thru the tubing, and insert the bolt. This makes the assembly much more secure than simply relying on the clamping force of the bolt to hold onto the slipped in piece of square tubing.Overall I'm very pleased with these connectors and when my next project needs ones I'll certainly buy these.

Worked as described

The other reviews are correct, the piece does not have an exact 90 degree bend, closer to 95. As a result, you will only be able to fit 2 of the 3 slots with a tube. However, due to the construction, you need all 3 slots to be fitted for structural rigidity.As a result, the piece is not usable unless you physically bend the connecter into the full 90 degrees. Not easy work because it's stainless steel, and not worth the effort for me, so I am returning this.

Es fácil y rápido su uso

I made an aluminum frame for my camping bed I used in my truck bed. It holds awesome and they kept together for a 6,000 mile road trips with some parts off road.All this to say they are durable and hold great!
