Caster Forks and Stems
NOTE: Different configurations achieve the desired front seat height based on caster size. If making
a change to front seat height or caster size, the combination of fork and stems could vary.
1. Install stem (A) into fork (B) with washer (C) and nut (D) using a 16mm wrench.
2. Install caster wheel (H) into fork (D) with two screws (E), a threaded barrel (F) and two spacers (G) using
two 4mm Allen wrenches.
NOTE: There are two sizes of caster stems (standard and +3/4") and three sizes of slotted forks
(short, standard and tall) and standard forks (4", 5" and 6") that can be used. The image below
shows the stems and forks. The installation process is the same for whichever stem and fork you
use.
