Using this oven door seal is easy. First, measure your oven door to figure out the right length for each side. Then, cut the 2 - metre long seal into 4 pieces according to your measurements. Fit the corner pieces onto the cut - seal pieces. Next, hook the seal into the holes in each corner of your oven. As a note, this seal has square corners, so it may not work well if your oven door has rounded corners. For maintenance, clean the seal regularly with a mild soap and water solution. Avoid using harsh chemicals as they can damage the seal. Store the seal in a cool, dry place when not in use to keep it in good condition. If you have any trouble fitting the seal, you can refer to the fitting - instruction video from eSpares in the UK.
