protect against moisture and contaminants
sometimes causes a hydraulic effect when the lamp
and plug are connected. This hydraulic effect can
prevent the plug from being fully seated in the
lamp, creating a potential leak path. Grease
Grooves allow the sealing compound to disperse
around the terminals with the excess sealant
escaping into the reservoir, eliminating the
hydraulic effect.
Durability
Every UBS component is designed to connect
securely and provide a strong, moisture tight seal.
Each plug is manufactured to precise tolerances
that enable the UBS system to meet or exceed
trailer industry standards.
Internal wire-to-wire connections are sonic welded
for a strong, efficient and reliable connection.
UBS plugs designed for Grote male pin lamps
use banded female terminals. Banded terminals
ensure that a solid electrical contact is created
and maintained each time a connection is made.
The bands provide a spring-like effect to the
female terminals in addition to ensuring an
excellent electrical connection. Banded terminals
are also used in UBS nosebox plugs to maintain a
secure fit.
Grote’s signature blue overmolding encapsulates
the connections providing critical strain relief and
they are virtually impervious moisture barrier.
Unique to Grote’s UBS system is the locking collar
used between the main & rear sill connection. The
rear sill collar locks the main harness to the rear sill
harness to avoid vibration and wear. Another
feature is the grease fitting which allows dielectric
grease to be applied to the connection.
Proven Reliability
Certified test results show the UBS system out-
performed competitive products in a tough
saltwater immersion and vibration testing
environment. Grote products went head-to-head
with the competition and had far fewer failures
than any challenger. As a complete system, the
LED’s and UBS system produced the highest pass
rate, lasting 39% longer than the closest
competitor. 100% of the Grote LED’s were
functioning at the end of the test.
Continuous Development
Grote continues to develop the UBS system to
meet the needs of those who demand the best.
Our male pin and double seal technology is
carried over into our newest designs resulting in
a single harness system that can be used for
either incandescent or LED lighting packages.
Plugs for incandescent, or LEDs offer simpler
electrical maintenance management; fewer
SKU’s in inventory and an optimized trailer
lighting system.
Exclusive locking collar prevents accidental
disconnects and provides a means of securing
the connection to the trailer
UBS offers a fully integrated, modular wiring and
lighting system.
