Many forms of off-the-shelf ladders will integrate directly with Utilihab framing, bolting directly to available slots. But for a more consistent design, the platform also supports their assembly from profile parts and pref-finished wooden components. In the domestic setting, this is most commonly used for access to lofts and for unusually tall shelving. In some cases, a ladder may be integrated into shelf structure. Utilihab uses two forms of ladders; a rigidly attached vertical ladder and a steeply-sloped latter-stairs sometimes referred to as a ‘ship’s ladder’.
The most basic ladder employs a pair of 50mm profile posts with 50mm profile rungs or treads. The runs are attached by through-bolts to threaded ends in the profiles for greater safety and may feature wood channel surrounds attached by countersunk bolts to t-nuts or snap-fit slot covers. This form of ladder is usually mounted flush between horizontal frame members or surface-attached to facing horizontal beams and can sometimes use Secondary posts as integral parts.
For easier access, off-set ladders are used. These are attached to facing framing members by profile posts, can employ dual rails to support wide treads, or employ a much wider side rail, allowing the side rails of the ladder to be extended to a hand rail at the top. This also allows for ladders over a walled area and with wider profile side rails, wider treads can be used. A side hand-grip profile can also be added to wide side rails.
Ships ladders use side rails as steeply sloped stringers for an open staircase of very short horizontal run and with narrow overlapping treads. The stringers are fitted with off-set hand rails that extend to a top hand rail, often with a curved profile shape like the hand rails of a swimming pool ladder. These are designed to be descended backwards, with both hands on the handrails, are usually mounted with some clearance of any side walls, and are not usually more than one meter wide.
