Fabric Shade Roller

Light-Duty Industrial Roll-Up Covers for Machine Guarding

Dynatect shade rollers (also known as “vertiflex” covers) are custom-made protective roll-up covers for machine guarding, consisting of coated or uncoated textile material attached to an industrial spring roller. Metal housing can be added to protect the roll-up mechanism. Shade rollers are a simple and cost-effective solution for involuntary contact with machine components and protection against UV light or occasional liquid and debris.

Dynatect shade rollers are ideal for applications where:

  • there is little room for other protective cover options,
  • simple mounting and retrofitting are required,
  • cost and delivery time are important factors,
  • high speed and acceleration are needed,
  • the complete seal of a bellows is not required
