30m Chalkline Rossel

is a tool used in construction and carpentry for creating straight lines over long distances. Here’s a breakdown of its features and usage:

1. Length: The “30m” designation indicates that the chalk line can extend up to 30 meters (approximately 100 feet), providing ample reach for marking long distances accurately.
2. Chalk Dispensing Mechanism: The chalk line consists of a reel mechanism housed inside a durable case or housing. The reel contains a spool of string or braided nylon line coated with chalk. When the line is pulled out and stretched, the chalk coating leaves a visible mark on the surface it contacts.
