DH-SMT, quick-fit slider lift, equipped with steel slide tubes in standard configuration from Dhollandia
• Standard = OAM064.S = Steel slide tubes + fixed mounting clamp position
• Optional (at cost) = OAM064.A = aluminium slide tubes with adjustable clamp positions
Besides manufacturing complexity, the aluminum slide tubes offer almost no weight gain in comparison to the steel ones. And the steel slide tubes offer 35 mm more ground clearance for equivalent slide frames. So aluminum slide tubes would only be advised when steel tubes are not possible for whatever reason.
