TYPE A: STEEL ADJUSTING RINGS
The versatile "Type A" Adjusting Ring is fabricated from steel and is used for any adjustment height desired, for any
type and size ring and cover, or when quantities desired do not justify the cost of a pattern for a cast iron "Type B"
Adjusting Ring. All bearing surfaces are machined to insure proper fit and prevent covers from rattling.
ALL ADJUSTING RINGS ARE MADE IN ONE CONTINUOUS PIECE TO MINIMIZE INFILTRATION OF WATER.
TYPE B: CAST IRON ADJUSTING RINGS
The "Type B" Adjusting Ring is made from cast iron and is used when the adjustment height is 1" thicker than the
cover seat. This adjusting ring is restricted to specific adjustment heights and is limited to certain standard size rings
and covers. Please contact our Customer Service Dept. for a recommendation on your particular application. All
bearing surfaces are machined to insure proper fit and prevent covers from rattling.
