The 1/4" by 1" cylinder is one of our most popular sizes due to its great versatility. The D4X0DIA-N52 is a little different in that it is diametrically magnetized, which means the curved sides will attract instead of the flat ends. And since it's Grade N52, you know it's as strong as can be!
This size is also available
axially magnetized in Grade N42 as part number
D4X0 and in Grade N42 with a small dimple on the north end as part number
D4X0-ND.
