Unit Isolator Anchor™

Unit V Drive-On Anchor™
The Unit V holds under all types ofconditions, even in frozen or where
it counts most – below the ball of therail, and low down on the tie. The continuous rail-bearing design eliminates
unnecessary contact stops and stresspoints and assures proper set on therail base every time – without damage
to the rail. The custom steel sectionused to make the Unit V has rounded edges that prevent slivering andchipping in case of mis-hits and thewider hitting area means anchors go
on with less effort. The Unit V DriveOn Anchor’s proven design ensuresbetter spreading and re-boxing during
mechanized crosstie changeouts tominimize labor costs.

Unit Spring Anchor™
For more than 80 years the Unit Spring
Anchor has been the answer tolongitudinal rail movement under thetoughest circumstances – heavy axle
loads, curvature and steep grades.
The initial and retained holding
power of the Unit Spring Anchor are
unmatched by any other rail anchor
or fastener available. Application byhand is easy and safe, using the patented Unit E-Z Wrench, or by production anchor equipment.

Developed to minimize longitudinalrail movement on concrete ties withelastic fasteners, the Unit IsolatorAnchor attaches to the Unit V DriveOn Rail Anchor. It acts as an insulator
and anti-friction device prohibiting therail anchor from damaging the tie’s
surface, while providing full bearing
area and full longitudinal restraint. The
Unit Isolator carries the profile of theconcrete tie, is symmetrical and may
be applied on either side of the tie andon the gauge or field-side flange ofthe rail. It takes up the load from theresilient fastener as a result of pador insulator wear compromising thetoe-load of the clip. Unit Isolators havebeen installed on Class 1 Heavy-Haulrailroads in tangent track aroundbonded joints, in curves, at bridge
abutments and in turnouts – everywhere there is a critical need to provide signal isolation and control rail
movement. Unit Isolators are deliveredin bags and preassembled and readyfor installation by sledgehammer or
automated equipment.
