Very impressed with the quality!
Color: Silver Size: 4PCS 600mm(23.6'')
I bought 6 sets of these in different lengths and am highly impressed. Sturdy, precisely formed, cleanly cut, individually wrapped in protective plastic, then boxed. They all arrived in excellent condition, no dings, dents or bends. There were a few minor burrs on the ends from the cutoff saw, but they were so minor 1 or 2 strokes of a fine file removed them. Honestly, if I didn't have a file I could have left them as is--VERY nice! ... show more

Good product

They worked for my purposes. Easy to cut with a small ryobi bandsaw. Used these to make a stand for my case and bullet feeder. I will buy again.

Great quality rails for custom desk setups and DIY frames
Color: Silver Size: 4PCS 600mm(23.6'')
I ordered two 4-packs of the 600mm (23.6") silver extrusions to frame out a custom, heavy-duty sliding under-desk keyboard tray. Build Quality & Finish • Straightness: All rails arrived perfectly straight with zero bowing or twist, which was critical for ensuring smooth, bind-free linear slide movement. • Surface & Cut Ends: The silver anodizing is clean, consistent, and scratch-resistant. The factory cut ends are square and clean with minimal burring, meaning very little prep was needed before bolting things together. • Slot Fit: Standard European-spec 20-series hardware (drop-in T-nuts, roll-in spring nuts, and standard M4/M5 hardware) slid into the slots without binding or excessive play. Shipping Experience There was an initial fulfillment mishap where two boxes arrived, but one box was completely empty. However, Amazon customer service resolved the issue right away and sent out a replacement set without hassle. Once the replacement arrived, the build came together quickly. The 2020 profile provides plenty of rigidity to eliminate bounce and sag under hand pressure while keeping the keyboard tray assembly lightweight and low-profile. A solid choice for 3D printer parts, desk attachments, or general maker builds. ... show more

VORON users-pay attention to END TAPS
Color: Black Size: 4PCS 700mm(27.56'')
I bought these to make a top-hat for my Voron Trident. There's nothing wrong with the extrusions. Be careful though: The outer dimensions are the same as what you would see from an LDO kit, but the center hole cannot be tapped for M5. You'll have to tap the center for M6. Make sure you have the hardware on hand. Also, these are anodized aluminum with a perfectly reasonable finish, but if you compare it to the finish of your LDO kit you will be disappointed. ... show more
