Rollers. It was in our rental and they yanked on it till it fell off. It could only be latched from the inside so I'd like to add a keyed lock. I bought a replacement at a big box store but the latch amd key part we're centered in the middle between the acre holes and ours is off center. Not positive if it's higher or lower. I've attached a bunch of pictures. Please let me know if you have something.
Thanks so much!
Linda
