Drawer Slide Load Rating and Length Selection

Start with cabinet depth and drawer construction

Nominal slide length should be checked against cabinet depth, drawer depth and installation clearance.

Undermount slides and side-mounted ball bearing slides use different drawer construction, so decide the slide family before finalizing the drawer box.

Load rating needs context

Load ratings should be compared with the same installation style and test assumptions. The expected drawer contents and use frequency should be included in the RFQ.

For office storage, wardrobes and kitchen drawers, note whether the load is light, standard or heavy duty.

Confirm extension and closing function

Specify partial extension, full extension, soft-close, push-open or standard function. Each option affects cost, installation and available models.

For mixed-length orders, provide quantity by length and model family.

Useful RFQ attachments

Cabinet sections, drawer dimensions, target slide samples, quantity schedules and packing needs help speed up quotation.

Supplier evaluation

Compare quotations on specification, not unit price alone

Two cabinet-hardware quotations are only comparable when the product configuration is the same. Check dimensions, material, finish, mounting method, load or door data, closing function, accessories and packing quantity. A lower unit price may reflect a different model, missing accessories or lighter packing.

Ask the supplier to reference every quoted item to the drawing, BOM or target sample. Record open questions separately from confirmed specifications. This makes technical review faster and prevents an unconfirmed assumption from becoming part of the purchase order.

Order control

Use approved samples and stable item references

Before bulk production, confirm a sample or a documented reference for each important configuration. The approval record should include the item code, revision date, drawing, finish, accessory pack and packaging format. Photos are useful supporting evidence, but dimensions and functional requirements should remain the primary reference.

For repeat orders, keep the approved item code unchanged unless the specification changes. If a substitution is proposed, review it as a new configuration instead of assuming equivalence. Stable references improve receiving checks, reduce installation questions and help purchasing teams compare later quotations.

For a drawing-based quotation, send the available PDF, DWG, DXF, product photo, BOM and quantity through the CabFitCo RFQ form. Include the destination market and required delivery schedule so packing and consolidation can be reviewed with the product specification.
