How and when to fit rising butt hinge

Hanging a new door in the home doesn’t have to cause a headache, providing you have the correct tools and the right hinges. Avoid the time-consuming task of looking up a tradesman and get that sense of accomplishment by doing it yourself!

 

What is a Rising Butt Hinge?

Each hinge consists of two parts; the leaf that is fitted to the door frame which has a spiral knuckle and pivot pin, and the second flap which is fixed to the door. Once each leaf is fixed in position, the door is lifted, and the hinge pin will slot into the knuckle.

As the door is opened the leaf fitted to the door rides up the spiral knuckle raising the door a few millimetres.

 

 

Left, or Right?

Rising Butt Hinges are handed (either left or right) and you must choose the correct option to suit your door.

 

If the door opens away from you and the hinge is to be on the left, then use a left-handed rising butt hinge. If the hinge is to be on the right, then a right-handed hinge will be required.

 

 

However, if the door opens towards you, reverse this and choose a left-handed hinge for the right side or a right-handed hinge for the left.

Most hinges will be marked RH or LF so as not to confuse.

 

When to use?

Thick or Uneven Door Ways

If you have deep piled carpet or some other thick floor covering or uneven flooring in the doorway or jamb area that prevents the door from easily opening and closing, then this is a perfect situation for rising butt hinges.

Designed so that when the door is opened, it raises high enough to clear the thickness of the carpet. These may also be used outside the home wherever the door or gate lies below the level of rising ground.

Keep in mind, that when installing a rising butt hinge in this situation, you’ll also need to make sure that the installation height of the hinges are fixed precisely to keep the bottom of the door from pressing down and rubbing the thick floor covering when the door is being closed.

When an easily removable door is wanted

Another situation when you may wish to use a rising butt hinge is when you want to fit a door that can be easily removed. Due to the design of rising butt hinges, a door can easily be lifted off the hinges (when it has been installed correctly). This is useful when decorating, cleaning carpets, moving furniture through the house.

Self-Closing Door?

These hinges have the advantage over ordinary butt hinges in that the door becomes almost self-closing. The weight of the door combined with the bevel on the hinged joint can sometimes cause the door to close by itself. They won’t cause the door to automatically close fully, every time, but people will usually notice that the door is closing behind them and complete the task themselves.

 

How to Install rising butt hinges

  • To mark out the fixing position of the hinges, the hinge should be laid flat against the edge of the door and the recess. Take care in marking these dimensions precisely. When done, the recessing should be equal on both the edge of the door and the frame.
  • After measuring the width and depth of the hinges in the appropriate position, handsaw and gouge out the recessed area with a sharp wood chisel and mallet. Be sure to use a sharp chisel and take extra care whilst doing this bit.
  • Rising butt hinges should be placed approx. 150mm from the top and bottom of the door.
  • Where possible, get help to support the door as you offer it up and check the fit in the doorway. You should allow at least 2mm clearance around the door to prevent sticking. You may need to allow a bit more if the floor is particularly uneven.
  • The fitting of rising butt hinges follows pretty much the same fitting procedure as for standard butt hinges, but with rising butts, the door will need some additional trimming to provide a suitable gap between the top inside corner of the door and the top inside of the door frame. This provides adequate clearance for when the door rises.
  • This is done by measuring 6mm down from the top inside corner of the door and draw a diminishing line to the outside corner and the inside corner of the door. This should then be planned off the door, working inwards.
  • Because the door has been trimmed on the inside edge means that the diminishing gap will be hidden when the door is in the closed position.
  • If you find the door still meets the door frame after removing this amount, simply trim a little more off the door.
