HOLLAND FWS1 Top Plate

Simple Lock Adjustment

Simple and quick lock adjustment pin with 4 incremental positions, reduces the risk of over-adjustment.

NoLube Pocket Inserts

Austempered ductile iron NoLube pocket inserts provide greater durability with freer articulation.

Improved Release Handle

Closed release handle design improves driver ergonomics, and requires less force to operate.

Jaw Return Spring

Jaw return spring has been added to prevent the jaw from closing while bobtailing.

Visual Safety Indicator

Visible 'red' safety indicator provides driver with an easy, clear visual indication that the wheel is properly coupled. There is also an automatic secondary locking mechanism.

Air Release


The Holland fifth wheel air release system provides a simple, easy-to-operate, in-cab fifth wheel lock release system. With just a simple pull of a dash-mounted air switch, a pneumatic cylinder on the fifth wheel will effortlessly open the locking mechanism.

SAFE: Three-stage system ensures that the fifth wheel lock release can only be operated when the vehicle’s parking brakes are engaged. The unique air-assisted interlock design absolutely prevents accidental release of the fifth wheel lock, while still allowing manual release operation if necessary.

EFFICIENT: Reduces the time your driver spends manually locking and unlocking the fifth wheel. Less manual interaction with the fifth wheel (and the grease that can come with it) limits potential driver injuries that can lead to expensive worker’s compensation claims.

CONSISTENT: Backed by SAF-HOLLAND’s extensive five year parts and labor warranty, the air release system will work reliably when you need it to – every time.
