A King Cobra screen wedge should be replaced with a part that matches the shaker’s wedge-retention arrangement, screen configuration, and physical dimensions—not simply one that looks similar. Before ordering, identify the shaker and screen model, inspect the existing wedge and contact surfaces, and compare the replacement’s shape and measurements with the original or the equipment documentation. At Yuanpeng, we recommend confirming compatibility with clear photos and dimensional information before production or shipment. This guide explains what to check, how to replace a worn wedge safely, and what information to provide when sourcing a replacement.

This guide is for drilling contractors, screen distributors, maintenance teams, and procurement professionals responsible for shale shaker screens and related retention parts. It is useful when a wedge is damaged, missing, difficult to secure, or being sourced as part of a screen replacement. It can also help buyers check a proposed substitute before placing an order. Because shaker designs and screen assemblies vary, the guide is not a substitute for the equipment manufacturer’s instructions.
A screen wedge is a mechanical retaining component used in a screen installation system. Depending on the shaker configuration, it helps hold a screen assembly in position against its support or sealing surfaces during operation. Its fit matters: a wedge that is too loose, incorrectly shaped, or mismatched to the assembly may not retain the screen as intended. A wedge is not necessarily interchangeable across all King Cobra-related equipment or across other shaker brands.
Compatibility may depend on the wedge profile, contact surfaces, retention method, material, and the screen or shaker version. Two parts can have similar overall dimensions but differ in a notch, taper, end shape, or seating angle that affects how they engage. Confirm the complete interface rather than relying on a product name or a single measurement. If the original part is unavailable, equipment identification and reference drawings become especially important.
Replacement wedges may differ in material and manufacturing details, depending on the design and intended service conditions. A buyer should ask the supplier to identify the offered material and confirm whether the part is designed for the relevant equipment interface. Do not assume that a material or finish is equivalent just because two products are described as screen wedges. The correct specification is the one that matches the required fit and operating conditions.
| Item to verify | What to check | Why it matters |
|---|---|---|
| Equipment identity | Shaker model, screen type, and available part reference | Names and configurations may vary between versions. |
| Wedge profile | Taper, notches, ends, and contact faces | These features determine how the part engages. |
| Dimensions | Length, width, and height, recorded in mm | Comparable measurements help identify size differences. |
| Condition | Deformation, cracks, wear, corrosion, or damaged seating areas | Visible damage may indicate a broader retention problem. |
Record the equipment model and any screen or spare-part reference shown in the manual, parts list, or existing purchase documentation. Note whether the screen is the same type and configuration as the one currently installed. If the machine has been modified or has mixed components, tell the supplier rather than assuming the original configuration remains unchanged.
Remove the part only in accordance with the equipment maker’s maintenance procedure, and inspect it for wear, bending, cracking, or missing features. Also examine the areas where it seats, since damage or contamination there can affect fit even when the replacement wedge itself is correct. If the wedge is missing or too damaged to measure, collect information from the screen assembly and equipment documentation.
Measure the wedge’s length, width, and height in mm, and note any taper, groove, notch, or other distinctive feature. Where possible, take measurements at 3 positions along the part to show whether its profile changes from end to end. Measurements are reference information, not proof of compatibility on their own, so include a photo with a scale and a clear view of the mating profile.
Ask the supplier to confirm the intended equipment or screen configuration and to compare the proposed part drawing or sample with your reference. Check the profile and contact points, not only the stated overall dimensions. If any detail is uncertain, resolve it before ordering a batch rather than relying on a visual impression after delivery.
Follow the shaker manufacturer’s service instructions and use the specified installation method. Do not force a wedge that does not seat correctly, and do not compensate for a poor fit with improvised packing or unapproved modifications. After installation, check that the screen is retained as intended before returning the equipment to service.
Ordering by name alone: A matching product description does not establish that the geometry matches your particular assembly.

Measuring only one dimension: Length alone cannot describe a tapered profile or identify differences in notches and contact faces.
Ignoring the screen and support condition: Wear, debris, or damage around the seating area may affect retention even when the replacement wedge is correctly specified.
Assuming cross-brand interchangeability: A wedge that appears similar may use a different retention interface. Request confirmation against the relevant equipment information.
Replacing without checking the cause: If a wedge has deformed or repeatedly becomes loose, inspect the associated screen and seating components and consult qualified maintenance personnel.
Price and availability depend on the confirmed design, material, order quantity, and whether the part is standard or requires customization. Minimum order quantity and lead time should be confirmed directly with the supplier for the specific specification; they should not be inferred from a general product listing. For a more useful quotation, provide the equipment model, required quantity, destination, preferred material if specified, dimensional reference, and photos or drawings. If timing is critical, ask the supplier to state the estimated production and dispatch schedule separately.
Before approving a supplier, check whether they can explain how they will verify the wedge profile and what reference information they need from you. Ask whether they can provide a drawing or dimensional confirmation for your review, and clarify how material and packaging will be identified. Confirm how the supplier handles questions about fit, changes to specifications, and inspection before dispatch. These steps help make the order requirements explicit without relying on unsupported claims of universal compatibility.
When you contact Yuanpeng, include the shaker model, screen type, quantity, and any part number available. Add the wedge’s dimensions in mm, close-up photographs from 2 angles, and a photo showing how the part sits in the assembly when safe and practical to capture. If you have a drawing or a known reference sample, mention it when requesting a quotation. We can review the information with you and clarify which details are still needed before confirming a replacement proposal.
Compatibility depends on the equipment and screen configuration, wedge profile, and mating surfaces—not just the product name.
Record length, width, and height in mm, and document distinctive geometry with clear photos or a drawing.
Ask the supplier to confirm the proposed part against your reference before ordering, especially when the original wedge is missing or damaged.
To evaluate a King Cobra screen wedge replacement, first identify the shaker and screen assembly, then compare the original or documented profile with the proposed part and verify the installation method against equipment instructions. If the fit is uncertain, do not force the component or assume it is interchangeable. Send Yuanpeng your equipment details, dimensions, photos, and quantity requirement to discuss a suitable replacement and request a project-specific quotation.
