#84 Favourite Brick Friday: 2449 Inverted Slope 2x1x3
The Inverted Slope 2x1x3 a special kind of slope. It is inverted and has an angle of 75 degrees, but unlike other slopes it has 3 anti-studs on its opposite side.
This allows you to attach it to plates that are 3 studs long, or on any other plates but at their ends. This will let you utilize the technique of SNOT (Studs Not On Top) so you can build sideways. The connection is also fairly strong because of the 3 studs. As well as this, you can attach details and supports to the anti-studs as seen in the picture which makes this a versatile piece to use in your MOC.
