Advertised to fit internal dimensions of 60mm x 23mm (which is my stair case) but these legs measure where they fit the stair case is a 56 x 20 mm, resulting in a very loose ( unsuitable) suited. The size should be 60 x 23 (or 1mm larger) to ensure a tight fit. Even extending the step sole only increases it to 59mm so I'm not sure I can fit them in and they won't slide all the way into the ladder's leg after weight is placed on them. The ledge for the stepped leg should be approximately 64mm x 27mm to avoid shifting in the leg. And since one side is hollowed out, there isn't enough material to thread the bolt through the ladder's leg to hold it in place, a viable option.
