Do you need something bigger than a compass for your construction blueprint? Get a trammel from HomElectrical, the electrical supply store, to meet your applications needs.
A trammel is used with a beam to make up a beam compass. These tools are typically used to scribe a circle and the radius. It can be adjusted by sliding the metal across the wood and locking it in place. Choose from our selection of competitively priced trammels for all your measuring and layout needs.
