A:Answer The current 27" washers and dryers that use the LG 27" Laundry Stacking Kit, Model # KSTK1 that is exactly the same as the now discontinued RSTK1 all have the exact same dimensions as the LG Front Load SteamWasher™ with 9 Washing Programs, Model # WM2487HRM and the LG SteamDryer Electric Dryer, Model # DLEX7177RM which has a depth that is 1/4" deeper than the other units, but if it worked with the RSTK1, then it should work with the KSTK1 because the only difference between the stacking kits is the color. RSTKI is red and KSTK1 is chrome.LG only makes the chrome stacking kit now...^IFV
