How to Install Drapery Rods Extender

If you have a drapery rod that is as long as you can buy, but still not as long as you need, an extender is the answer. A properly designed extender requires little extra effort to fit.

Step 1 – Read the Instructions.

Read the instructions that came with the extender.

Step 2 – Fit to the Rod

An extender that is properly designed will be shaped and engineered so that it will simply slide inside one end of the rod. Once in place the extended rod can be measured and the surplus length cut off. Always cut the surplus off the rod extension. This will reduce the distance from the end to the joint and avoid any problems of the drapery getting snagged if it is moved along the rod.

Step 3 – No Extender

If can not buy an extender you will have to make one. To do this you will need the following materials

  • Original curtain rod
  • Tape measure
  • Piece of hollow tube the same external dimension as the rod and as long as the necessary extension
  • 18 inch dowel the diameter of the internal diameter of the rod and extension (or the greater if they differ)
  • Duct tape

Step 4 – Clean ends

Clean the ends of both the rod and the extender. There should be no sharp ridges.

Step 5 – Insert the Dowel

Insert the dowel into the end of the rod. If the dowel is a loose fit make it tighter by wrapping duct tape around the first 9 inches. When there is a tight fit, push the dowel into the rod. Lock the dowel in place by driving a short nail through the tube into the dowel.

Step 6 – Connect the Extender

Insert the dowel now sticking out from the rod into the extender. If the fit is loose use more duct tape to make a tight fit. Make sure that the ends of the rod and extender are flush together and then lock the dowel in place by driving a short nail through the extender into the dowel.

Step 7 – Sanding the Dowel

If in steps 5 and 6 the dowel is too wide to fit into the rod or the extender, coarse sandpaper must be used to reduce the diameter of the dowel. This is a much better way of securing a good join because there is no need to try to force a rod and an extender of similar diameters to mate. The dowel adds to the over all strength.

Step 8 – Smoothing the Join

If there is a noticeable ridge at the join you should use fine glass paper to smooth it away.

Creating a join in a rod and an extender in this manner gives a much more pleasing appearance if the rod can be seen. Even if the drapery is going to be moved along the extended length of the rod there will be no danger of a snag. With 18 inches of reinforcement inside the rod and extender join there is no danger that the join will distort, even in the long term.
