SeekLiny 26pcs 2020 Corner Bracket Connector Aluminum Extrusion Hardware V-Slot T-Slot Accessories with T Nuts and Screws for 8020 Aluminum Profile 3D Printer Frame Accessories Black

Solid aluminum corners, works well

Brackets and 8mm screws are perfect for my 1515 extruded aluminum. However, the T-Nuts will not work. I'd have to indivually reshape them to work-very time consuming.

Strong and lightweight. Used these on my roof rack build as additional support. Great deal for all the parts you get

After disassembling my printer to install the t-slot nuts, many would not fit in the track. One had really messed up threads and the rest had quality control issues and were dented on either the ends or the center edges of the nut and would not fit.

Worked well with my 2020 extrusions. For some reason the brackets were covered in oil. Has to degrease them before using. The screws were also oil soaked. Had one bad t nut but luckily I didn't need all 26 brackets.

These brackets are nice and sturdy and will add rigidity. All hardware is nice quality and everything has a good fit and finish.

Big printers move alot and barely have any bracing... this solves that. only 4 stars because the hardware is terrible... strips if tightened too much. use better bolts with these brackets and lock nuts.

Ordered these twice the first set was great, so I ordered another set. None of the t nuts from the second set will fit in my profiles.

The media could not be loaded. Edit, after leaving review seller contacted me and sent the missing hardware straight to my door, excellent customer service! Bought two sets now both times they were short a bag of m8 bolts (26) for a total of 52 short kinda sucks mid way threw a project

Will be using these to construct support columns.

We are using these to strengthen corners and as hangers in the greenhouse. They fit perfectly and are strong enough to tie up plants along wallls. Will order again.
