Review on 80 20 4 Hole Inside Bracket by Mark Jefferson

Overall, this 4-hole wedge provides a stronger grip in corners than a 2-hole wedge. This is a Series 10 part, meaning it has a 1" profile (to accept extruded 1" beams such as 80/20 Inc., 1010, Series 10, 1"x 1" 48 Customs service). The 1 inch bar I ordered was smaller than what I saw at the factory. But there is another series of parts, Series 15, that is thicker and stronger than this because it is based on a 1.5" profile (designed for 1.5" diameter extruded beams). Series 15 parts are NOT interchangeable and cannot be used with Series 10. They cannot be used as a replacement for 15 series parts and vice versa. However, if you're a beginner, starting from scratch, and don't have anything like me, you're not trying to replace anything, so it's best to decide ahead of time which series you're going to go with. switch completely to series 15. For this reason I have listed 80/20 15 Series 4336 4 HOLE INNER WEDGE CORNER KUSSET. Alternatively, if you're ok, carrying heavy loads, or worried that one of those little cloths might fail (i.e. you need even more link strength), and starting from the very beginning with the 15th row, you can use one of the link plates like here too See: 80/20 15 Series 4351 5 HOLES 90 DEGREE JOINT PLATE .
