    Adjustable Curtain Dock Seal
    Lenworth Dock Seals
    Lenworth Technical Data
    Technical Data
    • Curtain Options: Adjustable and fixed curtains
    • Materials: Vinyl, memory foam, pressure treated wood, and galvanized steel


    Designed to work best where doors are over 9’ H and/or where trailers vary in height, the 0201 is an economical way to form an air tight seal between the building and trailer for dock openings up to 10’ W x 12’ H. For added versatility, the Series 0201 is also available with an adjustable head curtain that can be easily positioned by one person from inside the building by means of rope and pulley after the trailer is in position. The resilient foam pads can be covered with a large selection of tough abrasion resistant fabric, creating a tight seal that blocks foul weather, insects and dust, while saving money on energy costs. The Series 0201 Dock Seal will also protect personnel, product and equipment while increasing comfort, safety and productivity.

    Features & Benefits

    At Lenworth, we’ve paid close attention to the details so you get the best product possible. For example, the yellow guide stripe on the Adjustable Curtain Dock Seal is vulcanized (heat sealed), not sewn on, and the seals are customized to ensure perfect sealing. We also offer adjustable curtains for trailers with varied height, and fixed curtains for standard highway trailers, and all of our seals are long-lasting and low-maintenance.


    The Adjustable Curtain Dock Seals feature long lasting, high quality vinyl with u.v. stabilizer to prevent fading. High density memory foam compresses on all sides, reducing the potential for damage. The backing is made of the highest quality pressure treated wood, and wrapped in vinyl, and the mounting brackets are made of galvanized steel.
