The Slide On 3447i Hinge (TH52 Pattern) brings whisper-quiet, hydraulic soft-close operation to the classic and secure Slide-On mounting mechanism. Designed specifically for cabinet doors between 14 mm and 25 mm thick, this hinge provides high structural stability and smooth daily performance across kitchen units, wardrobes, and commercial cabinetry.
With its 105^\circ opening angle, the 3447i opens wide enough for comfortable access to internal shelves without swinging into neighboring units or walls. The integrated dampening system catches the shutter mid-flight and pulls it to a silent, gradual closeÃÆ’Æ’¢ÃÆ’¢â€šÂ¬ÃÆ’¢â‚¬ÂÂÂÂÂÂeliminating shutter bounce and noisy impacts.
The TH52 cup pattern (35 mm cup cutout with 52 mm screw spacing) ensures compatibility with modern cabinet manufacturing standards. Equipped with multi-axis micro-adjustment screws, installers can easily fine-tune door height, depth, and side alignment on-site for clean, uniform reveal gaps.

1. What does the "i" in 3447i mean?
The "i" stands for Integrated Soft-Closing. The hinge has an internal hydraulic damper that prevents cabinet doors from slamming, guiding them to a quiet, soft stop.
2. How does the Slide On 3447i differ from the Onsys 4447i?
Slide On 3447i: Uses a Slide-On mounting system (the hinge arm slides over the base plate and locks in place with a screw).
Onsys 4447i: Uses a Clip-On mounting system (the hinge snaps on/off the base plate tool-free).
3. What does the TH52 drilling pattern indicate?
TH52 specifies that the two mounting screw holes on the hinge cup are positioned 52 mm apart (center-to-center) around the standard 35 mm cup hole.
4. Can the soft-close feature be turned off if not needed?
No, the hydraulic damper is built directly into the hinge arm and works automatically on every closure.
5. How many hinges are required per door?
Recommended hinge counts based on door height and weight:
Up to 900 mm height (under 7 kg): 2 hinges
900 mm – 1600 mm height (7–12 kg): 3 hinges
1600 mm – 2000 mm height (13–19 kg): 4 hinges
2000 mm – 2400 mm height (20+ kg): 5 hinges
