The places where a cabinet or wardrobe fails are rarely the panels. They are the hinges that sag, the drawer slides that catch and the doors that sit a few millimetres off. Hardware is a small part of the order by value and a large part of how the product feels when a client opens a drawer for the first time. This checklist covers the specific checks to run on hinges, slides and door alignment when a unit arrives or before it ships.

Why Hardware Inspection Pays for Itself

Furniture hardware is inexpensive to replace and expensive to fix once it is assembled into a finished unit in a container. A hinge that is under-rated or misaligned is a small component, but fixing it after arrival means dismantling, reworking and re-packing, which costs more than the part. A short checklist against the hardware catches those problems before the container is sealed. Our furniture inspection checklist covers the wider process that this hardware work sits inside.

Check the Hinges: Count, Duty and Movement

A cabinet door is normally hung on at least three hinges, and a wide, tall or heavy door needs more than that. Count the hinges on every door and check that the count and the weight of the part match. A wide wardrobe door on two hinges is a problem waiting to develop, because gravity pulls the door out of square over time. Then test the movement. Open and close each door; it should swing freely without binding and sit flat against a straight edge when closed.

Hinge Levels and How to Read Them

Not all hinges carry the same duty. Cabinet hardware is graded for the load and cycle life it can sustain, so a hinge that suits a small wall cabinet may not hold a heavy interior door. Match the hinge to the door weight and keep a note of the rating for the record. The distinction matters when a supplier substitutes a lighter hinge after the sample is approved.

The standard that cabinet hardware duty is measured against is worth knowing before you order, because how hinges and slides are graded changes the long-run cost of a run. In the United States, cabinet hardware is defined by the ANSI/BHMA A156.9 standard for cabinet hardware, which sets performance tests for hinges, drawer slides, pulls and catches across operation, cycle life, strength and finish.

Test the Drawer Slides: Rating and Track

Drawer slides carry a weight rating and a typical side-mount set is rated in the region of 20-35 kg, with heavier full-extension runners supporting more. Pull each drawer fully open and then push it home. The track should run for its full length without a drop, the box should not rub on the frame, and the two slides should sit level so the drawer does not skew. A drawer that rides to one side shows a slide that is set too tight or a box that is out of square.

Reading the Track Gap and Full Extension

Small tolerances decide how a drawer feels. The gap between the drawer box and the frame is measured rather than estimated, and the front gap between doors is held to an even small allowance. A drawer that catches, even slightly, points to a distorted box or a slide that is not parallel. Full-extension hardware should let the drawer come right out for access; a runner that stops short is a value question, not a defect.

The placement of hardware is part of the build quality. Everything from how a drawer is supported to how a wide unit is braced is covered in our factory audit checklist.

Check Door Alignment and Gaps

With the doors in place, run a hand along the front face. Doors should sit on the same plane, neither set back nor proud, and the gap between a door and the frame should be even top to bottom. A common allowance is a tight even gap of around 1.5-2 mm. Do the same between adjacent doors and across a run of drawers. Uneven gaps almost always trace back to a hinge that is not fully adjusted or a carcass that is not square, both fixable before shipping.

Sag, Bounce and the Soft Close

Close each door slowly and then let it fall. A damped or soft-close hinge should bring the door in quietly; a loud slam or a door that bounces back shows a damper that is worn, missing or never adjusted. Check the same on drawers with soft-close slides. The damper is a wearing part, so its condition is a good signal of the quality of the hardware set.

Check the Fit: Edge Banding and Surface

Hardware sits on a panel that has to be sound. Run a thumb along the edge banding on the doors and the drawer fronts. It should be flat with no lifting or cracked corners, because a panel whose edge is failing will push the hardware out of alignment as the substrate moves. Check for slivers of glue, an uneven finish and any chipped edges that would be obvious once the unit is in a home or a work space.

Test the Unit the Way It Will Be Used

The final check is behavioural. Open and close every door, pull every drawer and work the catches and pulls several times. A unit that feels right when it is operated flat on a factory floor can still be flawed once it is standing, so load the shelves and check the carcass for wobble. Doing this before the container is sealed is far cheaper than discovering it at the destination. Common cabinet defects and the fixes behind them are laid out in our five hidden QC risks and fixes article.

A checklist turns a vague impression of quality into a set of pass or fail points. The buyer who counts hinges, reads a slide rating, checks the gaps and operates every unit is the one who gets a product that holds up once it is installed. If you want a sourcing partner who checks these points on the factory floor before your cabinet shipment leaves, our services and pricing page explains the inspection levels we run.

Frequently Asked Questions

How many hinges should a cabinet door have?

At least three on a normal door. A wide, tall or heavy door needs more, because the additional hinge points stop the door from sagging and going out of square over time.

What weight should furniture drawer slides be rated for?

A typical side-mount slide is rated in the region of 20-35 kg. Heavier full-extension runners support more, so match the rating to what the drawer is meant to hold.

What is an acceptable cabinet door gap?

An even, tight gap of around 1.5-2 mm between the door and the frame is common. The key is that the gap is even from top to bottom rather than a specific number.

Why does my drawer rub or catch?

Usually a slide set too tight, a box that is out of square, or slides that are not parallel. Check that the slides sit level and that the box is straight before deciding whether the hardware needs replacing.
