^ Some great ideas and hacks, i_t_e, thank you for posting them here in this thread!
I didn't know that "Cobra Ties" were used to secure the Flexroute guides so that certainly lessens my previous concern. It does plainly state in the installations instruction that "the Flexroute is not intended for load bearing application" but I'm in agreement that it could probably handle 30-40 pounds, the same as a standard Superclamp. Plastic ties are pretty tough customers; since law enforcement has no reservations using them periodically as handcuffs, I'd think they're up to snuff for this application.
