Some things to consider when adding guard rail.

• Their primary purpose is prevent product from falling off the conveyor. However, sometimes they may be used to help guide the product. 
• If a guard rail is used to guide product, caution should be taken. If too many products, especially heavy items, are forced up against the guard rail they may overload the drive.
•  When product is up against a guard rail, it can hinder the flow of that product depending on a variety of product and conveyor drive factors. Consult us if you believe your product needs to rest against or be guided by the guard rails.
• If you have a considerable variance of product heights, special consideration may be required to ensure low products don't go underneath the rail and the guard is sufficient to protect tall products from falling off.
• Product overhanging the conveyor and the ability for the product to negotiate a curve must also be considered when selecting the type of guard rail.
• Curves should nearly always have a guard rail mounted to the outside radius to prevent product from falling off.
