## SpanTrack Lane FAQs
#### Why should I use steel carton flow rollers instead of aluminum? What is the cost difference?
Steel rollers are more durable than aluminum rollers and have a low slope needed for long runs. Steel rollers are more expensive, but they are built to withstand harsh environments and difficult workflows.
#### Can SpanTrack Lane be installed in freezers or climate-controlled areas?
Yes! SpanTrack Lane is freezer/cooler rated to below zero and is often used to store and flow temperature-sensitive goods. SpanTrack Lane is a popular choice for cold chain operations due to its freezer/cooler rating and durable, rugged construction.
#### How do I select the correct track width for SpanTrack Lane carton flow rollers?
SpanTrack Lane is available in 6 different widths (6", 9", 12", 15", 18", 24") and at varying capacities. Product width will be the primary factor in determining lane width. Product can overhang the lane, up to 3" on either side and maintain flow.
#### What are the different flow options and capacities for SpanTrack Lane?
SpanTrack Lane is offered in 3 main capacities or “series”. Our 98 series rollers are our lightest capacity tracks. 98 Series SpanTrack Lane carton flow rollers are .75” inches in diameter and can be made in aluminum or steel, and are rated starting at 35 lb. per linear foot. Our 99 series carton flow rollers are considered standard-duty and are typically the most common. 99 series rollers are rated starting at 50 lb. per linear foot. Our 100 series carton flow rollers are our heaviest-duty carton flow solution. 100 series SpanTrack Lane rollers are 1.38” in diameter and are made of galvanized steel with bearings. 100 series roller lanes are rated starting at 100 lb. per linear foot.
