These heater straps are excellent quality. They are well stitched, use a strong fabric, an elastic fastener to ensure a tight grip.
Note the length of this dew heater strap carefully. We always recommend you grab a measuring tape, and measure the length that you will require. It is okay if the dew strap is longer, but it must not be shorter and you can’t include the length of the elastic strap (which is 10cm).
