BLCCLOY 10Sets 10 Series 1" x 1" Aluminum Extrusion Profiles Corner 1010 Series Angle Bracket Connector with M6 T Slot Nuts Bolts for 1 Inch x 1 Inch Extruded Aluminium Profile Rail

Excellent finish.. It's true that it is made of aluminum.. won't rust..

The inserts are rather small and can spin in and out of the channel. You don't install these in the typical way, NO PRELOADING in fact! The best way to install is put the insert first ON the L bracket (the little bump out on the insert goes on facing the screw & L bracket), very loosely, just spin the inserts until they are attached on the screw. Then just insert into the channel and tighten in place. The insert will spin itself into the channel as it tightened. You can do this in captivated channels which IS VERY USEFUL! Now I am finding these easier to work with than the normal inserts. It is SPEEDING UP our campervan build, everything is adjustable as needed and that is perfect for min/maxing our Camper layout. It is nice to have the "spin in" option for use in captivated channels for an affordable price!!

The brackets are slightly thinner than name brand ones but the hardware was more robust than the more expensive name brand ones. Worked great and didn't have any flawed pieces. Will be buying again!

I needed "drop-in" or "roll-in" t-slot nuts for a project I was working on where I could not access the ends of the extrusion. I purchased this because it plainly states that they were included and pictured. I received standard t-slot nuts that have to be slid in from the ends or you would need to rout an access slot in the extrusion. It's frustrating because I ran out of time to return and order the correct product, so I had to use a Dremel to grind away aluminum to force these to work.Two stars because the brackets are functional and the hardware works, its just not what I needed or was interested in purchasing

Very light duty, would not personally use. I’m
