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.

Boats, yachts and offshore enclosures need drawer slides that survive salt spray, humidity and constant motion. This benchmark weighs AOLISHENG 304 stainless options — W2576 (500 lb / 227 kg), W2053 (265 lb / 120 kg) and the W5115 / U4510K soft-close lines — against the Sinohard SH5301 (SUS304, 115 kg) that ranks for “marine boat corrosion resistant drawer slides”. The standout: AOLISHENG’s W2576 carries nearly double SH5301’s load in the same 304 stainless.

Frequently Asked Questions

What makes a drawer slide marine-grade?

304 / SUS304 stainless (or a sealed corrosion-resistant coating) plus sealed ball bearings that resist salt spray and humidity.

What load do marine drawer slides need?

Cabin and galley drawers typically need 45–115 kg; heavier offshore storage uses the 115 kg class — and AOLISHENG’s W2576 reaches 227 kg in 304 stainless, nearly double a SH5301-class slide.

Does AOLISHENG make marine stainless slides?

Yes — the W2576 (304 stainless, 500 lb), W2053 (304 stainless, 265 lb) and W5115 (304 stainless, 150 lb) lines suit cabin, galley and offshore storage.

How does AOLISHENG compare to Sinohard SH5301?

SH5301 is a 115 kg SUS304 slide for heavy offshore storage; AOLISHENG’s W2576 is 304 stainless rated 500 lb (≈227 kg) — nearly double the load at the same material grade — so offshore lockers get far more headroom, while the W2053 / W5115 lines cover the 45–120 kg cabin and galley segment with soft-close options.

Should marine slides be soft-close?

Soft-close (U4510K) reduces slamming in motion — a practical upgrade for cabin and galley drawers on a moving vessel.
