Introduction
Casters are one of the most widely used parts and come in many shapes and sizes, often with a 4-hole mounting plate.
Challenges
Mounting the caster securely through all four mounting holes near a tri-joint (which tend to be at the corners of projects, exactly where casters want to be) isn't easily accomplished.
Approaches
-
Stronger caster joints
-
Weaker caster joints
One corner configuration secures the caster at two points and centers the vertical frame member on the caster. The other applies significant force, with the possibility of a bending moment on the caster mounting plate.
