The list above is for reference. It is crucial to verify the shape (wedge) and dimensions (176x92 mm) on your machine.
This pad is mounted with 2 bolts (usually part of an adjustment mechanism). When replacing wedge pads, it is also worth checking the condition of flat pads and applying fresh telescopic boom grease.
Worn wedge pads make it impossible to correctly adjust the arm play. This leads to telescope "wobble", which accelerates wear on other components and can lead to fatigue cracking of the boom structure.
The 2171577 wedge pad is used not only for guiding the extension but primarily for centering it and eliminating play. Thanks to its tapered shape, tightening the adjustment screws forces the pad against the inner arm section, removing unwanted clearance.

No, it is a wedge pad. Its thickness varies along its length (from 28mm to 59mm), which is used for play adjustment. Flat pads have a constant thickness.
Typically, a CAT telescope uses 2 or 4 wedge pads (for adjustment) and several flat pads. You should check the diagram for your specific model.
