There is a special rail slide on the Laser Line MFG DE Laser Rods for attaching the Laser Bracket.
The Laserline detector bracket allows the laser detector to travel the full working length of the rod.
This allows faster and easier readings because it takes the awkwardness out of having to loosen the detector, move the detector, then tighten the detector for each reading.
