Sneaking equipment into the gym

I really want to use one of those longer tricep extension ropes that allow for a full range of motion when you're doing face pulls, but my Mountainside Fitness only has the regular ones, what are my chances of successfully sneaking it into the gym and then just leaving it there for everyone to use and no one will even notice from Mountainside staff? Obviously I would spend enough to get good quality Equipment designed for high volume use, I would hate to put anybody in any kind of danger because I cheaped out.

Edit: got a great suggestion from the comments- going to use 2 regular length ropes on one clip and see how that goes
