The Stanley Level Set Xtreme 3Pc features secured vial technology with a full frame vial carrier design that protects the vials against drop damage. The continuous edge allows for easy drawing and scribing along the full length of the level. It includes magnified solid block plumb vials with 90% larger vials for better visibility and an aluminum body with a robust extruded aluminum profile. The removable end caps provide easier 90° angle/corner access, and the shock-absorbing end caps are rubber-moulded to protect the level from drop damage.
