The 2,710mm movement stroke is the distance the carriage travels along the SZ 12 rail between its fully closed and fully open positions. This determines the maximum door height the rail can operate: a 2,710mm stroke accommodates the full door panel travel plus the mechanical overhead space required for sectional panels to stack horizontally above the opening. For Abu Dhabi garage doors, the stroke confirms the carriage has enough travel to open any sectional door up to 2.5m high with normal fitting within the SZ 12’s rated limits.

The Marantec SZ 12 has a 3,330mm profile (vs 3,080mm on the Marantec SZ 11) and extends all height limits: overhead doors to 2.75m (vs 2.5m), sectional normal to 2.5m (vs 2.25m), and low lintel/tension springs to 2.375m (vs 2.125m). The SZ 12 should be chosen when the garage door height exceeds the SZ 11’s limits. Both use the same toothed belt, 0.8mm thickness, plain bearings, 2-piece design, and compatibility with the full Marantec Comfort range.

Standard Abu Dhabi villa garage doors are typically 2.0–2.2m high — within both the SZ 11 and SZ 12 limits. The SZ 12’s 2.75m overhead door height capacity is relevant for commercial properties, warehouses, showrooms, and parking facilities with taller vehicle clearance requirements — such as doors designed for vans, 4×4 SUVs with roof racks, or commercial delivery vehicles. For any Abu Dhabi garage door between 2.26m and 2.75m overhead height, the SZ 12 is the correct Marantec rail, and the SZ 11 cannot be substituted.

The rail selection depends entirely on door height and fitting type: choose the SZ 11 if the overhead door is under 2.5m or the sectional door is under 2.25m with normal fitting. Choose the SZ 12 if the overhead door is between 2.5m and 2.75m, or the sectional door is between 2.25m and 2.5m with normal fitting. For low lintel or tension spring fitting, the SZ 11 covers up to 2.125m and the SZ 12 up to 2.375m. Measure door height and headroom before ordering; an incorrect rail cannot be corrected after installation.

The Marantec SZ 12 is supplied in silver — the standard Marantec rail colour — with a 3,330mm profile length, 0.8mm material thickness, and 6 kg weight. Packing includes: 1× 2-part opener rail with rail connector, pre-assembled and installation-ready. No further assembly is required before fitting to a compatible Marantec Comfort operator. The SZ 12 is AED 560 versus the SZ 11’s AED 470 — a AED 90 difference for 250mm additional rail length and extended height capacity.
