7. The bracket of claim 1 , wherein the first end is a first distal end of the first arm, and the second end is a second distal end of the second arm.
8. The bracket of claim 1 , wherein the first arm includes a first hollow interior region that extends between a first set of opposed walls of the first arm, and the second arm includes second hollow interior region that extends between a second set of opposed walls of the second arm.
9. The bracket of claim 8 , wherein a first set of stiffening ribs extends across the first hollow interior region between the first set of opposed walls, and a second set of stiffening ribs extends across the second hollow interior region between the second set of opposed walls.
10. The bracket of claim 1 , wherein the alignment protrusion includes a hollow interior region that extends between an interior surface of the alignment protrusion, and includes a plurality of stiffening ribs extending along the hollow interior region between diametric ends of the interior surface.
11. The bracket of claim 1 , comprising a first flange extending in a direction opposite the alignment protrusion from the corner portion and the first arm, and a second flange extending in the direction opposite the alignment protrusion from the corner portion and the second arm, wherein the first flange, the second flange, or both, include a respective mounting aperture formed therein.
12. A bracket for stacking heating, ventilation, and air conditioning (HVAC) units, comprising:
a corner portion having a base surface and a plurality of walls extending from the base surface to define a first raised contact surface of the corner portion;
a first arm extending from the corner portion and having a second raised contact surface at a first end of the first arm, wherein a first strap surface extends between the first raised contact surface and the second raised contact surface; and
a second arm extending from the corner portion and having a third raised contact surface at a second end of the second arm, wherein a second strap surface extends between the first raised contact surface and the third raised contact surface, and wherein the first raised contact surface, the second raised contact surface, and the third raised contact surface are configured to support weight of an HVAC unit.
13. The bracket of claim 12 , wherein the first strap surface and the second strap surface are substantially coplanar with the base surface.
14. The bracket of claim 13 , wherein the first strap surface extends between the first raised contact surface and the second raised contact surface to define a first strap recess, and the second strap surface extends between the first raised contact surface and the third raised contact surface to define a second strap recess.
15. The bracket of claim 12 , comprising a plurality of stiffening ribs extending from the base surface and extending between the plurality of walls, wherein distal ends of the plurality of stiffening ribs form the first raised contact surface, and wherein the first strap surface and the second strap surface are substantially coplanar with the first raised contact surface.
16. The bracket of claim 12 , comprising a first flange extending in a direction opposite the plurality of walls from the corner portion and the first arm, and a second flange extending in the direction opposite the plurality of walls from the corner portion and the second arm.
17. The bracket of claim 16 , comprising a first strap chamfer formed on the first arm and extending between the first strap surface and the first flange, and a second strap chamfer extending between the second strap surface and the second flange.
18. The bracket of claim 12 , comprising an alignment protrusion extending from the base surface in a common direction with the plurality of walls, wherein the alignment protrusion extends beyond the plurality of walls in the common direction.
19. The bracket of claim 12 , comprising a first hook extending from the first arm in a direction opposite the plurality of walls and a second hook extending from the second arm in the direction opposite the plurality of walls, wherein the first hook and the second hook are configured to engage with edges of an HVAC unit top panel in an installed configuration of the bracket.
20. The bracket of claim 12 , wherein an angle between the first arm and the second arm is approximately ninety degrees.
