The metallic gray folding piston is an essential accessory to open smoothly closet or cabinet doors and that these mechanisms support the weight of these enclosures, without a problem. This piston is indicated for wooden and aluminum doors with 16 mm and 19 mm thick and straight cup hinge dimensions with 15 mm overlap. These dampers are recommended for doors with dimensions less than 450 mm, if the door exceeds this measure, 2 dampers must be used. It is made of steel and plastic with an aluminum-colored finish. Its opening angle can be 80 °, 90 °, and 100 ° with a total force of 12 kg. Packaging of 20 units.

HOW TO CALCULATE THE MOUNTING:
Add E+1 to calculate A and X, being E the thickness of the board.
• For wooden and aluminium doors.
• For overhangs other than 15 mm, calculate value A+15-overhang.
• For doors wider than 450 mm the use of 2 springs is recommended.

CALCULATING STRENGTH OF STAY:
F: Force supported by piston in kg.
P: Weight of door in kg.
H: Height of door in mm.
B: Fixing point of piston in mm.
F = (P x H x 0,6) / B

CALCULATING WEIGHT OF DOOR:
P = Weight of the door in kg.
H = Height of the door in cm.
A = Width of the door in cm.
e = Thickness of the door in cm.
d = Density of door material.
Particle board: d = 0,72 kg/dm3.
MDF: d = 0,75 kg/dm3.
Glass: d = 2,54 kg/dm3.
P = (H x A x E x D) / 1000
