The sensible hotwire probes can be safely protected against transport damages with the Touch Guard HWP-Pro while they're not in use. The protection itself is manufactured out of Poly Amid plastic. To apply the protection the probe needs to be inserted into the slot and get latched by the twist-lock. Then the probe can be pulled back into its final position.
The Touch Guard HWP-Pro is available in two sizes. The HWP10/90 and HWP10/45 probes need the smaller type, HWP-ProS. All other probes require the bigger HWP-ProM.
