【Strong and durable】: This self closing door hinge using space aluminum alloy, Hinge thickness 4mm, strong and durable, a pair of hinges can bear ≤50KG, The stable structure and good materials enable this hinge to have a longer service life. 【Function】:Our hydraulic hinge in addition to the basic hinge function，(1)Maximum door opening Angle 175°,if exceeds 160° will automatically reset to 160° door stop position (prevent touching the wall);(2)160°-90° is an arbitrary stopping Angle; (3)The door automatically closes at less than 90°. 90°-30° the automatic closing speed is faster，30°-15° the automatic closing speed is slow .15°-0°can be adjusted by the hinge function to choose push into lock or close quietly. like a Door Closer. 【bearing capacity】When the weight of the door is ≤ 50kg, use 2 hydraulic door hinges.When the weight of the door is ≤ 80kg, use 3 hydraulic door hinges.When the weight of the door is ≤ 100kg, use 4 hydraulic door hinges. 【Attention】:(1) When installing and debugging multiple hinges, pay attention to the adjustment efforts as much as possible to maintain consistency.(2)Pay attention to adjust the upper and lower hydraulic hinge pipe vertically and on the same center line.(3)When installing and debugging multiple hinges, pay attention to the adjustment efforts as much as possible to maintain consistency. 【Note】: Heavy hydraulic silent invisible self-closing door hinge in the production process using high-quality materials and sophisticated technology, and has been well tested. If you encounter any problems during use, please feel free to contact us and we will provide you with the best quality shopping experience. (Product equipped with detailed instructions)

hydraulic buffer hinge Specifications:

Angular interval function

• Maximum door opening Angle 175°

• Greater than 160° will automatically reset to 160° door stop position (prevent touching the wall)

• 160°-90° is an arbitrary stopping Angle

• Less than 90° will automatically shut down

• 90°-30° is the faster closing Angle

• 30°-15° is a slow closing Angle

• 15°-0° Fast closing and slow closing can be converted

Material:

space aluminum alloy

Surface process:

Black powder coating

Installation tips:

1.Hinge before installation and use, do not increase the force to break the hinge, otherwise the hinge is easy to deform.

2.Hinge installation is not divided into left and right, that is, left door and right door can be used.

3.It is recommended to install the hydraulic hinge 150mm below the top and above the bottom of the door. Install 3 hinges and install one more 450mm below the top.

4.When the hinge is installed, the hinge 25mm round shaft should avoid touching the door frame decoration strip.

5.Installation model (for reference)

• Door type                      Door weight            Quantity used

• General type                      ≤50KG         2PCS hydraulic hinges
• Heavy duty door               ≤80KG           3PCS hydraulic hinges
• Extra heavy duty door      ≤100KG         4PCS hydraulic hinges

6.When installing and debugging multiple hinges, pay attention to the adjustment efforts as much as possible to maintain consistency.

Installation sequence and slot depth

1. In the appropriate position on the side of the door (on the side of the door frame), the upper and lower two hydraulic hinge installation slots should be opened to ensure that they are in the same line and the same depth to prevent the hydraulic hinge installation from distorting and affecting the effect.

2. Install the hydraulic hinge close to the groove wall, draw 5 mounting holes and drill the bottom hole with a diameter of 3mm,the depth of 30mm, the upper and lower slots tighten the self-tapping screws, can not deviate too much, otherwise the screw sink head position can not be flat with the hinge surface, easy to resist the other side of the door or door frame, so that the door can not be completed to close the upper and lower hydraulic hinge installed on the same center line.

Key tips: Pay attention to adjust the upper and lower hydraulic hinge pipe vertically and on the same center line.
