If the FlexGuard just isn't working for you, try cable ties. I've used them under 2 different slides. I got rid of the flexguard entirely under the kitchen slide and used the cable ties wrapped loosely around the slideout arms. I watched those wires very closely the first few times I moved the slide to make sure nothing was binding or getting caught somewhere. Under the super slide, I also used a hinge on the end of the flexguard. At some point, that flexguard also broke in the middle. I drilled some holes in the edges, then ran more cable ties through - no problems.
