*Take note that UHD quick couplers have a special shape for optimal work-
ing range with Cat demolition work tools. Please contact your Cat dealer
for UHD couplers for non-current Cat machines.
**For operation under heavy working conditions, like rocky soils and demo-
lition work, we highly recommend the usage of quick coupler CW-45(S).
