8020, 1010, 10 Series 1 Inch x 1 Inch T-Slotted Aluminum Extrusion DIY Extruded Linear Slot Bar Rail 80/20 (Black Anodize, 24" Long)

I call this 8020 T-slot aluminum extrusion the "engineer's Erector set'! This member is strong, yet light weight anodized aluminum which makes it attractive and weatherproof. I am planning on using this over my small deck outside our bedroom. I will use this as framework for over the porch, sliding plexiglass panels in the slots, making an effective greenhouse. I plan on designing a vent in the system to exhaust the heat in the summer.

excellent rail for sport high power rocketry

Exactly what I wanted, as advertised!

Couldn’t find any issues yet, but I haven’t installed them either

Expensive

Factory fresh, well packaged. Shipping was expensive (oversized package) but what else is new.I have been using this stuff at work for the last 15 years and I learn something every day.Thank-you 80/20

Have purchased the 1.5"x1.5"x72" and now the 1"x1"x60". Using these to build cargo carrier supports for a Dodge van. These bars are light and super strong. Slots make them extremely versatile. Figuring out the correct hardware to use with these bars can be challenging but can be done with a bit of effort. Pricing isn't overly expensive UNTIL you add in shipping cost. Make sure to place a single order for everything that you need from 80/20 so that shipping cost is ALMOST acceptable (expect long delivery time). Pricing for the End Caps is crazy expensive. Best to look online for cap alternatives IMO.

it came protectively wrapped. Nice
