Self-positioning mechanism with locating template eliminates complicated installation • Integrated opening angle adjustment between 75° and 107° • Cabinet height from 10" (250mm) to 24" (610mm) • Interior cabinet depth minimum of 7-3/8" (187mm) • Arm has built in safety feature to prevent opening and closing • Secure lever are before installing cabinet • Max front weight 39 lbs for two lift mechanisms • When using a third lift mechanism (a power factor increase of up to 50%), Blum recommends a trial application • Note: Blum recommends for wide cabinets, an additional lift system should be attached to the center panel, to prevent the middle of the front from sagging when open • Determining power factor: Power factor = cabinet height multiplied by door weight
