Professional Fastening Solution for Transparent Sheets
The plastic discs with cap are specialized round spacers designed for mounting polycarbonate and other transparent structural materials. Each unit features a 40 mm diameter and a 6 mm hull diameter to ensure precise alignment. These components are manufactured from transparent, environmentally friendly plastic that resists UV exposure and temperature fluctuations. This set includes 25 pieces to support various greenhouse and canopy installation projects.
Preventing Damage During Sheet Installation
Fastening polycarbonate sheets directly with screws often leads to localized stress, cracking, or deformation of the material. Over-tightening can compromise the structural integrity and weather resistance of your greenhouse or canopy.
These plastic discs with cap solve this by evenly distributing the fastening force across the surface of the sheet. By acting as a protective buffer between the screw head and the material, they maintain a tight, secure connection while preserving the aesthetic appearance of your structure.
