Large quantities of large plastic anchor sleeves in general may need to be special ordered and may have a longer lead time associated with them. This is especially true for plastic anchor bolt sleeves for use with anchor bolts roughly 2-1/4” in diameter and up. Custom plastic anchor sleeves can also be made given enough time, depending the the brand of sleeve.  Often, it is easiest to use a larger or different plastic sleeve size with an anchor bolt if a different sleeve size is required.  Portland Bolt does stock a comprehensive line of sleeves through 3” diameter, so feel free to contact Kyle and he will be happy to check inventory for you.
