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.

Why Standard Slides Fail on the Move

A drawer slide in a stationary kitchen faces gravity and occasional pulls. In an RV, boat, or outdoor kitchen it faces constant vibration, shock loads, humidity, and salt air. Ordinary coated carbon-steel slides can loosen, corrode, or slide open mid-transit. Three features solve this: locking mechanisms, stainless steel, and higher load ratings.

Feature 1 — Locking Slides (Stay Put in Transit)

Locking heavy-duty slides hold the drawer in both the fully closed and fully open positions. AOLISHENG’s D7625 500 lb Locking Slides use a dual-lock design ideal for generator bays, toolboxes, and exterior compartments. Browse the full locking drawer slides range.

Feature 2 — Stainless Steel (Beat Corrosion)

Coastal and marine environments are the #1 cause of slide rust. Our W2576 500 lb Stainless-Steel RV Slides resist salt spray for exterior storage. See all stainless-steel drawer slides.

Feature 3 — Higher Load Ratings

Heavy gear — batteries, tools, outdoor-kitchen kits — needs real capacity. Options include:

A2576 500 lb Heavy-Duty Slides — RVs, outdoor kitchens, toolboxes.
A2071 330 lb Heavy-Duty Slides — DIY, workbenches, RV storage.

Selection Cheat-Sheet

Use case	Pick
Exterior compartment, heavy, must not drift open	500 lb locking (D7625)
Coastal / marine, corrosion risk	500 lb stainless (W2576)
