1. Product Overview
The Vestil D-750-24 Vinyl Dock Shelter is designed to provide an effective seal between a building and a truck trailer during loading and unloading operations. This unit helps to protect goods from environmental elements, improve energy efficiency, and enhance safety at the loading dock.
The top header is constructed from wolmanized lumber, engineered with a slope to facilitate water run-off. It measures 114 inches in width and includes a 30-inch drop curtain. The side verticals are 120 inches tall and feature high-density foam mounted to treated lumber. When installed, the face of the vertical measures 12 inches in width, tapering to 9-1/2 inches at the wall. The verticals are mounted on 2-inch by 12-inch wooden pieces, allowing for secure wall mounting along their length.

2. Safety Information
Always prioritize safety when installing, operating, and maintaining the Vestil D-750-24 Vinyl Dock Shelter. Failure to follow safety guidelines can result in serious injury or property damage.
- Professional Installation: It is highly recommended that installation be performed by qualified personnel familiar with dock equipment and building structures.
- Inspect Before Use: Before each use, visually inspect the dock shelter for any signs of damage, wear, or loose components. Do not use if damage is observed.
- Clear Area: Ensure the loading dock area is clear of obstructions and personnel before a truck approaches or departs.
- Proper Truck Positioning: Guide trucks to approach the dock slowly and squarely to ensure proper engagement with the shelter and prevent damage.
- Vehicle Restraint: Always use appropriate vehicle restraint systems (e.g., wheel chocks, dock locks) to secure the trailer before loading or unloading begins.
- Maintenance: Adhere to the recommended maintenance schedule to ensure the longevity and safe operation of the unit.
- Local Regulations: Comply with all local, state, and federal safety regulations and standards applicable to loading dock operations.

3. Setup and Installation
The Vestil D-750-24 Dock Shelter is designed for straightforward installation, but due to its size and the need for structural integrity, professional installation is recommended.
Pre-Installation Checklist:
- Verify all components are present and undamaged.
- Ensure the mounting surface (building wall) is structurally sound and capable of supporting the unit's weight and operational forces.
- Confirm dimensions of the dock opening and surrounding area match the shelter's specifications.
- Gather necessary tools and safety equipment.
Installation Steps (General Guidelines):
- Positioning the Header: Mount the top header unit above the dock opening. Ensure it is level and positioned to allow for proper water run-off as designed. The header measures 114 inches in width with a 30-inch drop curtain.
- Mounting Verticals: Attach the side vertical pads to the wall on either side of the dock opening. These verticals are 120 inches tall and contain high-density foam. They are mounted on 2-inch by 12-inch wooden pieces, which should be securely fastened to the wall along their length. The face of the vertical will measure 12 inches in width and taper to 9-1/2 inches at the wall.
- Secure Fasteners: Use the provided mounting hardware and ensure all fasteners are tightened securely according to the detailed installation instructions provided with the product packaging.
- Final Inspection: After installation, perform a thorough inspection to ensure the unit is securely mounted, all components are aligned, and there are no obstructions.

4. Operating Instructions
The Vestil D-750-24 Vinyl Dock Shelter operates passively by forming a seal around a truck trailer as it backs into the loading dock.
- Approach: Instruct the truck driver to approach the loading dock slowly and squarely.
- Engagement: As the truck backs into the dock opening, the trailer's rear will compress the foam-filled side verticals and engage with the top curtain. The built-in air tunnels within the pads allow air to escape, facilitating maximum compression and a tight seal.
- Secure Trailer: Once the trailer is fully engaged with the dock shelter and positioned against the dock bumper, immediately secure the trailer using appropriate vehicle restraint systems (e.g., wheel chocks, dock locks) before any loading or unloading operations begin.
- Departure: After loading/unloading is complete and the trailer is ready to depart, release the vehicle restraint system. The truck can then slowly pull away from the dock, allowing the dock shelter to return to its original position.
The maximum compression design ensures an effective seal, protecting the interior from weather elements and maintaining temperature control within the facility.
5. Maintenance
Regular maintenance is crucial for extending the lifespan and ensuring the continued effectiveness of your Vestil D-750-24 Vinyl Dock Shelter.
- Routine Inspection:
- Inspect the vinyl fabric for tears, punctures, or excessive wear, especially in areas of high contact with trailers.
- Check the foam pads for signs of compression loss or damage.
- Examine all mounting hardware for tightness and corrosion. Tighten any loose fasteners.
- Inspect the wooden components (header and vertical mounts) for rot, cracks, or structural compromise.
- Cleaning:
- Clean the vinyl surfaces periodically with mild soap and water to remove dirt, grime, and environmental buildup. Rinse thoroughly.
- Avoid using harsh chemicals or abrasive cleaners that could damage the vinyl material.
- Repairs:
- Small tears in the vinyl can often be repaired with a vinyl repair kit. For larger damage, contact Vestil or a qualified service technician for professional repair or replacement.
- Address any structural damage to wooden components immediately to prevent further deterioration and ensure safety.
- Winterization (if applicable): In cold climates, ensure that ice and snow do not build up on or around the shelter, which could impede its function or cause damage.
