One of many tools essential for performing carpentry and general construction tasks, the chalk line device is designed to mark straight lines with finely ground chalk. By tautly stretching the chalk line string over a distance and quickly plucking the string, construction workers release the chalk contained in the string. The visible line left behind makes it easy to accurately cut and trim drywall, plywood, and other materials used by carpenters and construction technicians.
Unfortunately, chalk line tools do not always work as expected. Common problems associated with chalk line devices include string breakage, the inability of the string to hold sufficient chalk, and the buildup of moisture on the string that degrades chalk. In addition, the wind-up crank used to retract the string is slow and prone to jamming up when moist or excessive chalk accumulates in the winding mechanism.

Introducing SPIDERLINE–the Most Advanced Chalk Line Tool Ever Invented

Tired of dealing with the aggravation of imperfect chalk line tools, seasoned construction industry professional William Calvert decided to take action and invent the perfect chalk line tool–SPIDERLINE.

How Does SPIDERLINE Work?

Calvert designed this clever chalk line tool with a separate gear drive box for the crank handle. This prevents the gear box from ever being exposed to chalk and also eliminates annoying jam ups. With a crank gear mechanism providing a seven-to-one (7:1) gear ratio, the SPIDERLINE offers rapid winding of the string after snapping. Inventor William Calvert further incorporated a convenient, flip out crank with a push-button release that makes it a breeze to wind up the line.

Features and Benefits of SPIDERLINE

The SPIDERLINE’s innovative chalk line string is made of diamond-braided cotton material capable of holding enough chalk so that you get a highly visible, straight line each time you snap the line. Moreover, the tool itself is made of durable, top-quality metal that will stand years of heavy wear-and-tear and daily use.

 These features and more make SPIDERLINE the #1 choice for construction workers, carpenters, and DIYers. No more dealing with faulty chalk line tools that can delay the completion of a project or cause imperfections in the finished project. No more expensive do-overs or wasting materials. In fact, SPIDERLINE is soon to be found in every carpenter’s toolbox as a must-have device!
