What is the difference between side mount and undermount drawer slides?

Side mount slides fix to the drawer sides and cabinet walls — easy to fit and tolerant of cabinet tolerances. Undermount slides sit beneath the drawer box, hide the hardware for a cleaner look, and need a compatible drawer box with the right reveal. AOLISHENG builds both: side-mount heavy-duty series (2053 / 2576 / 7625) and undermount soft-close series (MK316 / U4510K).

What does full extension mean compared with 3/4 extension?

3/4 extension leaves the back of the drawer still inside the cabinet; full extension brings the whole drawer clear of the cabinet face so you can reach the back corner. Most AOLISHENG heavy-duty and soft-close series are full extension.

How do I choose the load rating for a drawer slide?

Add the heaviest realistic contents, then add 25–30% headroom so the slide is not run at 100% of its rating every day. AOLISHENG ratings run from 100 lb (U1245) through 265 lb (2053 family), 330 lb (2071), 500 lb (2576 family) up to 770 lb (AQ7625K3 twin-slide).

What are soft-close drawer slides and when do I need them?

Soft-close slides use a damper that pulls the drawer shut in the last few centimetres, preventing slamming. They are most noticeable on kitchen and bathroom cabinetry and also reduce the shock load that gradually loosens a carcass. AOLISHENG soft-close options include K2053, U4510K and MK316.

Are stainless steel slides worth it for outdoor or marine use?

Yes — whenever the slide is exposed to weather, salt air, humidity or frequent wash-down (outdoor kitchens, marine galleys, food-prep, coastal installs). AOLISHENG stainless options include W2053, W2576, W5115 and U4510K.

Which AOLISHENG series number maps to which spec?

The stamped codes read: 1245 = 100 lb stainless side mount; 4510 = 100 lb stainless; 5115 = 150 lb; 2053 = 265 lb; 2071 = 330 lb; 2576 = 500 lb; 7625 = 770 lb twin-slide. Remove the drawer and read the code on the inner rail, or send a photo and AOLISHENG will match it.

Can heavy-duty slides be used in RVs, trucks and vehicles?

Yes, with a locking slide so the drawer cannot slide open under braking or cornering. Use locking series such as D5115, D2053 or D7625 for any moving-vehicle storage.

Invisible Soft-Close Drawer Slides for Retail Display Cabinets: A B2B Case Study

The B2B challenge: hardware must disappear in high-end retail fixtures

A retail fixture OEM building display cabinets for boutiques and showrooms kept losing bids because visible side-mount slides broke the clean lines of glass-and-wood cases. They also needed soft-close to protect fragile merchandise and prevent slamming in quiet retail environments. The solution had to be hidden, smooth, and reliable.

Why visible slides fail the aesthetic test

Side rails interrupt sight lines through glass cabinets and open shelving.
Slamming drawers risk damage to glass, jewelry, and electronics.
Inconsistent motion cheapens the perceived quality of the fixture.

The AOLISHENG solution: undermount and soft-close series for display cabinets

We specified concealed undermount slides where the look mattered most, and stainless soft-close side-mount where load or wash-down requirements demanded it:

Series	Load rating	Type	Lock / close	Best for
MK316	80 lb / pair	Undermount, soft-close	Soft-close	Premium display drawers, hidden hardware
A4510	100 lb / pair	Full-extension side mount	Non-locking	Standard retail cabinetry
U4510K	100 lb / pair	304 stainless, soft-close	Soft-close	High-traffic / humid retail environments
A2053	265 lb / pair	Heavy-duty full extension	Non-locking	Stock drawers and heavier merchandise

Results the OEM reported

Bid win-rate improved on premium fixture projects after switching to undermount concealed slides.
Soft-close reduced complaints about noise and impact damage in quiet retail spaces.
One supplier family covered light display drawers through heavier stock drawers.

Why B2B buyers choose AOLISHENG for fixtures

Concealed undermount slides preserve the designer’s intent, while graded load ratings ensure the hardware is not underspecified. Stainless soft-close options extend the same clean feel to humid or high-traffic retail environments.
