Set of lane numbers 1-7. White numerals on black 60 mil durable rigid plastic. 5" x 7.75". We call these "camera" numbers because they are preferred by professional timing vendors as they reduce glare on the Finish Lynx camera. Fits perfectly in bow clip. Printed with waterproof, UV ink to resist fading. A great gift for your favorite sculler! Also available in black on white, custom colors or with personalization and/or logos or graphics. RegattaPrint is the "go to" supplier of bow numbers for most major regattas and regatta organizers.
