There was no shrouding on the the gate...SO...We have a difference between the hw35y, hx35w and the he351cw. Anybody, please respond. I have nothing to remove!! (Just go to the t3 actuater dual imput.. in My case) and get on with it. It would help others if this is resolved. Anybody else have a reflection on the differences between the 3 units? Again, there is little difference between the puck and the hole--2mm. Thanks,Roger...no BIG deal, but just wondering.
