Hettich Slide On 3447 Hinge - T42 for 14-25 mm thick doors; Opening angle 105 Degree

The Slide On 3447 Hinge (T42 Pattern) is built to deliver smooth, long-lasting performance for modern cabinetry. Designed specifically for medium to thick cabinet doors spanning 14 mm to 25 mm, this hinge offers structural stability without placing undue stress on the door material.
Featuring a 105degree opening angle, it opens wide enough to eliminate awkward side-angle reaching while preventing the cabinet door from swinging into adjacent walls or neighboring unit doors. The T42 cup pattern (with standard 35 mm cup diameter) integrates smoothly with standard modular furniture processing machinery and jig setups.
Whether you are building new modular kitchens, bedroom wardrobes, or commercial office storage, the Slide-On assembly mechanism allows installers to mount the base plate first, slide the hinge arm into place, and lock it down securely with minimal effort. Combined with a corrosion-resistant nickel finish and micro-adjustment screws, the 3447 hinge keeps your doors aligned and operating smoothly over time.

1. What does "T42" mean for this hinge?
"T42" refers to the drilling distance between the two mounting screw holes on the hinge cup—specifically 42 mm apart. When ordering or drilling cabinet doors, ensure your cup pattern matches a standard 35 mm cup hole with 42 mm center-to-center screw spacing.
2. Can I use these hinges on standard 18 mm MDF or Plywood doors?
Yes. The hinge supports door thicknesses from 14 mm up to 25 mm, making standard 18 mm (or 3/4-inch) plywood, MDF, particle board, or blockboard doors ideal for this hardware.
3. How many hinges do I need per cabinet door?
The required number of hinges depends on the height and weight of your door:
* 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
4. What is the difference between a Slide-On hinge and a Clip-On hinge?
* Slide-On Hinges: Mounted by sliding the hinge arm onto the base mounting plate and tightening a retaining screw. They are very sturdy, cost-effective, and less prone to accidental dislodging.
* Clip-On Hinges: Snap onto the mounting plate tool-free with a spring-loaded trigger, allowing faster removal of doors without a screwdriver.
5. Does a 105^\circ opening angle prevent doors from hitting adjacent walls?
A 105^\circ angle provides a slight open overshoot beyond a square right angle (90^\circ) to allow easy hand access inside. If a wall or another cabinet sits directly flush adjacent to the hinge side, consider using door-stop bumpers or a angle-restriction clip to prevent contact.
