RONDO series – product features
for narrow stile doors
Spring-supported WDL project hardware guarantees a maintenance-free bearing system for lever handles (= "Wartungsfreie Drücker-Lagerung" = 'WDL'). Axial pulling forces are absorbed due to a very large bearing surface. Radial stresses are absorbed by an 8 mm long, toothed fixing element that holds the lever; the resilient and robust fixing element is patented. The WDL bearing system also features a lubricant reservoir.
Approved in accordance with EN 1906, grade 4.
