Blum AVENTOS HK with TIP-ON - Lift Mechanism Set - Power Factor 175-349 - 20K2700TNA

Lift Mechanism Set Set includes: - Lift mechanism (qty 2) - #7 x 35mm (1-3/8") wood screw (qty 10) Note: It is recommended to use the more powerful lift mechanism for overlapping areas. Power factor: 175 - 349 Opening angle: 107° (Can be restricted with optional angle restriction clips) Per Blum the formula for determining the power factor is door height in inches x door weight in pounds (including twice the handle weight) = Power Factor. For example, a 20" high door with a weight of 15lbs (which includes twice the handle weight) would be 20 x 15 = Power Factor 300.
