“I decided to try this 24" extension on my RML 490C and was surprised how well it matched up. Rogue doesn't currently have a plate storage addition for the rack so I took a chance and ordered one. Only short coming is the thickness of the Titan upright bottom pad is slightly thicker then the Rogue. This on my rubber padded floor created about a 1/16" gap between the floor and the bottom plate. Due to the thinner bottom cross member from the Titan extension leaves the rack somewhat unstable. What mean is you can slightly move the rack by pushing on it in the middle at the connection point of the extension. I mitigated this by adding plates to the middle portion of the rack and this helped. A shim would work as well or if a second pair of 3x3 cross members are purchased to replace the Titan logo cross members adding additional stability. Over all I am pleased with the purchase and hope this helps someone else make a decision to buy or not buy one for their RML rack.”
