Metal Angle Brackets (8 pack)
Here's a convenient package of 8 (eight) small plated-steel metal brackets, at about half the price of similar sized brackets at the hardware store. Their rounded ends make them more attractive than the typical metal bracket.
Width is 3/8"; thickness is 1/16" (approximately 16 guage), and therefore very strong. The L-shape has slightly uneven dimensions: 11/16" in one direction ("leg"), and 5/8" in the other. Pre-drilled for #8 screws. The slightly longer leg has a 5/16" long slot.
We use these brackets in a number of out kits. Weight is a low 2.6 grams each.
