Using these Gardner Bender 46 - 206M cable ties is a breeze. Just wrap the tie around the cables you want to bundle and insert the end through the locking mechanism. The DoubleLock design will secure it tightly. When using, make sure not to expose the ties to temperatures outside the -40 to 85C (-40 to 185F) range, as this could affect their performance. For maintenance, there's not much to do. Just keep them dry and away from sharp objects that could cut or damage the ties. These cable ties are built to last, but proper use will ensure they serve you well for a long time.
