1 folding piston, 1 side hook, 1 hook for Wood door, 1 hook for aluminium framed door, mounting screws

Pistons for furniture that enable the opening of wooden doors or those with an aluminium frame. They provide dampened folding of the fold-up door in kitchen, home and bathroom furniture. These shock absorbers are supplied in individual bags with assembly instructions. Each bag contains a piston, a catch for the side, a catch for wooden door, a catch for aluminium frame door and the necessary screws.

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

We have a table for calculating the weight of a door, which is necessary to know when choosing guy ropes and measurements. Depending on the material of the door, as well as its dimensions, the result will be the weight of the door (kg) that you can use to calculate to the necessary strength of the measure (Kg x cm).

For the same force required in both folding and lift up doors, we recommend that you only use a single piston or damper in a door with a width of less than 450 mm, and that you use two pistons or dampers for a door that is wider than 450 mm.

We have a table for calculating the pistons or dampners, where you can obtain a response with the furniture data. The choice will depend on the width and the height of the door, as well as the material it is manufactured out of, in addition to the stroke of the piston or damper itself. The result will be the number of pistons or dampners and the necessary strength of each one.
