The Flex-HD pull strap was designed as a way to help operators close their doors while remaining unobtrusive when securing the door. Attached to both the bottom panel of the roll-up door and the sidewall of the compartment, this pull-strap allows you to easily and safely close the door—reducing staff injuries and downtime—while also making the door easier to secure without a strap in the way, improving efficiency. The Flex-HD pull strap is available in a variety of lengths to suit a range of door heights. Suitable as either an OEM or retrofit option.
