Gripper Rods

Gripper rods are used around the perimeter of the room to be fitted with carpet. They are fixed at the edges of the room a short distance from the wall. The underlay will be fitted first, up the gripper rods and the carpet fitted over the underlay and stretched over the gripper rods and then tucked into the gap formed between the wall and the gripper rods, the carpet is then trimmed to size. When the opposite wall is fitted with carpet, the fitter will use a tool called a stretcher to pull the carpet tightly onto the gripper rod to ensure a neat, smooth finish to the carpet.

There are different types of gripper to suit different types of carpet and are available for wooden and solid floors. They are made of plywood and nails in strips which are fitted with the sharp points pointing towards the wall thus providing a fitting point for the carpet.

In the doorways, a metal door bar may be used to make a neat finish to each room. The door bar should be sited beneath the door in such a manner that it will be hidden when the door is closed.


Fludes carpets special select there underlay to give all round comfort and performance of your new flooring.

We use a PU Foam underlay which is recycled and can also be recycled after use.

We have selected the most used underlay we have but other underlays are available in store.

How to measure an irregular shaped room

The easiest way to do this is to draw the shape first and then fill in the lengths of the different walls.

Use a pencil and Ruler for drawing the shape and when you have the basic shape, mark on the drawing the position of doors and any cupboards in the room. At this point you should make a note of the type of flooring (IE. Solid or Wooden) and whether it is smooth or uneven.

Measure the maximum length of the room and the maximum width. Measure into any doorways and remember that the flooring will finish under the closed door so that from either side of the closed door you will not see the flooring on the other side. Fill in the rest of the sizes of all of the walls. If the walls converge into a “V” shape make sure that you measure from this point to the nearest other walls. Remember to check if the walls drop back from the room, for example into an alcove or beside the fireplace. Also check the gap under any doors to ensure that there is room for the carpet (& underlay)  to be fitted, and that the door will easily open when the floor is re-layed.

You should add about 10 cm or 3 inches to each wall length and not mix up the type of unit of measurement (either use centimetres and metres or feet and inches). Finally, check each wall shown on the diagram to ensure that you have not missed any sizes out.
