Mason's Line MEGA 100 m - model 61801, durable nylon string for layout and leveling

MEGA Mason's Line 100 m (model 61801) is a 100‑metre nylon layout string designed for construction and masonry tasks. The continuous durable nylon cord provides a visible guideline for marking, aligning blocks and bricks, and checking straightness and level on building sites. Its length and tensile strength make it suitable for long runs and repeated on‑site use when a reliable reference line is required.

Advantages

The nylon material resists fraying and offers good abrasion resistance on rough surfaces, while maintaining flexibility for easy handling. The 100 m length reduces the need for frequent joins, so one spool can cover extended walls or fence runs. The cord’s visibility and consistent diameter help produce accurate alignments and repeatable results without complex setup.

Suitable for

• Setting out and aligning masonry courses (brick, block, stone)
• Checking straightness and level across long runs
• Temporary fencing and boundary marking on construction sites
• Carpentry and formwork layout where a straight reference is needed

Key specifications

• Material: nylon cord designed for durability and abrasion resistance
• Length: 100 metres continuous line for long runs
• Diameter: consistent cord thickness for stable alignment (typical masonry line gauge)
• Handling: flexible for tying knots and anchoring to stakes or pins
• Storage: wound on a spool for compact transportation and controlled dispensing

How to use

Secure one end of the line to a fixed point or stake at the start of the run and unspool the cord to the second reference point. Keep the line taut and, if necessary, snap a chalk line or use a line level to check horizontal alignment. For masonry work, position the line at the appropriate course height and use it as a guide for laying bricks or blocks. After use, wind the cord back onto the spool to prevent tangles and protect the line from dirt and damage.

Usage recommendations

For best results, avoid dragging the line directly over abrasive surfaces for extended periods and store the spool in a dry place to prolong cord life; inspect the line regularly for frays before critical measurements.
