The Kleen Opener is a device designed to assist in the opening and closing of dumpster lids, aiming to improve user convenience and safety. It is primarily intended for use with various types of dumpsters, including those with metal angled, metal flat, plastic flat, and plastic lip top rails. The system utilizes a gas spring mechanism to facilitate the lifting and lowering of the lid, reducing the physical effort required from the user.

Function Description:

The core function of the Kleen Opener is to provide an assisted opening and closing mechanism for dumpster lids. Once installed, the device uses a gas spring to help lift the lid when initiated by pulling an orange strap. To close the lid, the user pulls down on the strap until the lid is fully closed, at which point it will remain shut. This mechanism is designed to prevent the lid from slamming shut unexpectedly and to hold it open for easier waste disposal. The installation process involves assembling an arm composed of an adapter tube, an intermediate tube, and an end tube with an eyelet bolt, which then attaches to a mounting bracket on the dumpster's top rail. The arm's length is adjustable to accommodate different dumpster sizes and lid configurations.

Important Technical Specifications:

While specific dimensions and weight capacities are not explicitly detailed, the manual highlights several key components and their roles:

Arm Assembly: Consists of an adapter tube, an intermediate tube, and an end tube with an eyelet bolt. These tubes are designed to slide into each other for length adjustment.
Mounting Bracket: The primary attachment point to the dumpster. Its design varies based on the dumpster's top rail material and configuration (metal angled, metal flat, plastic flat, plastic lip).
Gas Spring (black): The central component responsible for providing the assisted lift and controlled closure of the lid. It is initially secured with a nylon tie during shipping for safety, which must be removed after mounting.
Pull Down Straps (orange): Two straps are included, used to initiate the opening and closing actions. An extra strap can be attached for longer reach if needed.
Fasteners:
- Clamp Bolts (1/4" x 1"): Used to secure the intermediate and end tubes once the desired arm length is set.
- Mounting Bolts (1/2” x 1 3/4"): Used to attach the mounting bracket to the dumpster.
- Nylon Lock Nuts with Flange: Used with the mounting bolts for secure attachment.
Threadlocker: A chemical compound applied to the mounting bolts to prevent loosening due to vibration or movement, ensuring a secure installation.
Torque Washers (for plastic dumpsters): These washers have four sharp prongs that pierce the inner and outer walls of plastic dumpsters, providing a secure grip for the mounting bracket.
Spacer and Supporting Angle Bracket (for plastic lip dumpsters): Additional components used to accommodate the specific geometry of plastic dumpsters with an inner lip, ensuring proper bracket alignment and support.

Usage Features:

Assisted Lid Operation: The primary feature is the gas spring assistance, which makes opening and closing heavy dumpster lids significantly easier and safer.
Adjustable Arm Length: The arm can be adjusted to achieve the optimal length for various dumpster sizes, ensuring proper function and lid opening height. A 1-2 inch gap between the eyelet bolt and the front rail is recommended for correct positioning.
Left and Right Side Kits: The Kleen Opener is available in specific kits for both left and right sides of the dumpster, ensuring proper orientation and function. Tubes are labeled accordingly.
Strap-Activated: The orange pull-down straps provide a simple and accessible way to operate the lid.
Secure Closure: Once the lid is pulled down completely, it will remain closed, preventing accidental opening.

Maintenance Features:

The manual does not explicitly detail ongoing maintenance features but emphasizes proper installation for long-term functionality. The use of threadlocker on mounting bolts suggests a design intended for secure, long-lasting attachment, minimizing the need for frequent re-tightening. The robust construction with metal components implies durability. Users are advised to handle the product with caution during unpacking and installation due to metal edges, which could be considered a safety aspect related to handling and potential wear. The instructions for tightening bolts until "FIRM and SNUG" and until "the gap closes" are critical for ensuring the stability and longevity of the installation, thereby reducing the likelihood of premature wear or failure. The inclusion of extra pull-down straps suggests that these components might be subject to wear over time and are easily replaceable.
