Dewalt Preassembled V3 Lower Housing Auto Cup

Dewalt Pre-Assembled Lower Housing Auto Cup    Replacement Bottom Housing for Version 3 Mini Light that is pre assembled and ready for operation, needs to be plugged into version 3 Upper tray Housing.  Suction Cup Options     Small 4x3 Oval Cup or Large 5x4 Oval Cup   Recommended Cup Size For Auto Operation We recommend 4x3 Oval Cup for smaller 14" lights and larger 5x4 Oval cup for larger 20" lights. When you have an AutoCup you can push the suction cup against the panel letting the battery powered pump automatically create the suction for you making it much easier to start and create vacuum.  Since the auto cup reduces the main issue the larger cup has with a manual pump, we like the increased holding strength when paired with larger bulkier lights.     Recommended Cup Size For Manual Operation When using a Manual Cup Option we recommend the smaller 4x3 oval cup overall. It's a little larger than standard 3" round cups giving you better vacuum without added difficulty finding proper placement as the larger cups might have.  The oval design keeps an almost identical footprint as 3 inch round so it should fit almost anywhere the 3" round can if you properly align the longer side corresponding to the panel.  The main issue with Larger Cups when using a manual pump is it takes several pumps to start and complete the vacuum process. Combining this with added difficulty of getting a proper seal to start the vacuum process will increase time spent trying to position and set the light.    All Items Included In Pre Assembly   1x BBPDMAN - Bottom Base Plate for Dewalt V-3 Manual Cup 1x TBPV3 - Top Base Plate For Suction Cup V-3 (Fits All 3 Available Battery Types) 1x DIMCIRV3 - Elim A Dent LED Dimmer & Driver Circuit For V-3 Mini Light 1x V3USB2A - USB Circuit for V3 mini lights Fast charging 5v 2A output 1x PumpCirV - Elim A Dent Pump Sensor Circuit For V-3 Mini Light 1x V3AUTOPUMP - Auto Vacuum Pump for V3 Mini Lights  1x PSWITCH - V3 Mini Light Auto Cup Power Switch   1x CHKVALV - Version 3 AutoCup Check Valve   1x SCLA - Spinal Lower Assembly (3/4 Npt, 15 Single Sockets) 1x SCUA - Spinal Upper Assembly (3/4 Npt, Double Socket, Elbow) 1x SCSOCK - Spinal Cord Sock 1x SRV3 - V-3 Lower Slip Ring Wire Harness 12 Circuit (For 6 Led) 4x BBSCRW-  Base Screws For Elim A Dent V-2 & V3 Mini Light  Your choice of one below 1x 43OPAD - 4"x 3" Oval Suction Cup Replacement Rubber Base Pad 1pc 1x 54OPAD - 5"x 4" Oval Suction Cup Replacement Rubber Base Pad 1pc   Item# DPALAUTO43 Item# DPALAUTO54
