Basic Red Dot Timer Marking System-Waterproof, Indoor
Even in pouring rain, you'll know exactly where your electric eyes need to be. No more measuring or guessing. Just turn on your system, place the dot on the top of your electric eye, and you are ready to race!
This system comes with two waterproof red dot lasers, two swivel mounts, an adapter and installation instructions. Please choose an option for steel beams or wood rafters so you receive the best bases for your swivel mounts. All you need to provide is inexpensive low voltage wire available at your local home improvement store. We like 2-wire thermostat wire or door bell wire. Speaker wire works too!
