A stepladder accessory that allows a stepladder to be configured for use on a stairway or inclined surface. The accessory is a stabilizer that is adapted for removable mounting to a stepladder. The stabilizer includes securement means, mounting structure, and a telescoping support structure. The securement means and mounting structure can be integrated.

A rotation control mechanism comprises a first rotating member, a second rotating member, and a first locking pin. The first rotating member is provided with a pin hole. The second rotating member is provided with a locking hole. The first locking pin is inserted into the pin hole and the locking hole to lock the first rotating member and the second rotating member. The first locking pin and the first rotating member are circumferentially limited and movably arranged in an axial direction. A first elastic member is connected to the first locking pin and applies an action force to the first locking pin to be inserted into the locking hole. The second rotating member is provided with a trigger portion, and the first rotating member is provided with an elastic braking portion. The folding ladder comprises two ladders and two rotation control mechanisms.

A self leveling stepladder with a universal hinge joint providing many new advantages that traditional a-frame step ladders are not capable to offer.

The invention provides a coupling device (1), for a ladder having a bore in a headstock (4) extending between a pair of spaced apart styles, the coupling device (1) comprising: an elongate support member (6) having a mounting region (8) and a working region (7), the mounting region (8) configured to be received within the bore of the ladder to engage therewith, the working region (7) being configured to protrude from the bore and to receive and support a plurality of utility modules; and a releasable detent (9) to secure the elongate support member (6) within the bore, wherein the mounting region (8) is restrained from rotational movement relative to the bore, and the releasable detent (9) prevents longitudinal and transverse movement between the elongate support member (6) and the bore. The coupling device (1) of the invention provides a flexible ladder assembly that is adaptable to variable work environments encountered at the top of a portable ladder when used for access and conducting work.
