What does it do?
The T-25 carries the larger staples with rounded tops that allow you to quickly and easily pin phone wires and TV or computer cables to your walls or baseboards. You hold it against the wire, pull the trigger and the staple goes right in around the wire, binding it tightly. We use this to clean up cordage from phones, stereos and even television cables.
You can get various size staples for various thickness of cable. If you get really carried away, you can try the bigger T20 or T50! But the T25 is the multipurpose solution that works well in homes. Available for @ $29 at most hardware stores and online.
