The trend has rubber feet on its base ,, also I found that 2 work best with heavy doors and at least the door is level for planing but I’ve not had any issues with it slipping forward using electric planer or handheld traditional planes -I would however use a non slip mat or dust sheet on laminated or polished flooring. Approx 25 doors used of various weights.I usually put the end of my block against the door casing when I’m planning so it doesn’t move forward, how well does the Trend version resist forward thrust?
