Types of Configurations

STANDARD - Typical foot traffic in maintenance, access, pedestrian applications.
CLOSE-MESH - Same usage as Standard, just stronger, if you need to hold to a certain depth.
ADA-COMPLIANT - As the name suggests, provides a max ½" gap per ADA requirements.
HEAVY-DUTY - Configured to support heavy loading, such as vehicular traffic, via thicker bar.
HD CLOSE-MESH - Similar to Heavy-Duty, just closer bars for greater strength should the bar depth be limited.
WIDE-GAP - In certain situations, such as filtering operations, a wider gap is desired. Gap is 1-⅞".
EXTRA-WIDE-GAP - Same as previous. Gap is 2-⅜".
