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.

Frequently Asked Questions

What stainless grade should medical cart drawer slides use?

304 / SUS304 stainless is the clinical standard — it survives daily wipe-downs with alcohol and chlorine disinfectants and resists rust in humid rooms.

What load capacity do medical cart slides need?

Most procedure and supply carts carry 45–80 kg across a few drawers, so a 60–68 kg rated slide is the safe choice. AOLISHENG W5115 is rated 68 kg — more headroom than HVPAL HA3504’s 60 kg.

Does AOLISHENG make stainless medical cart slides?

Yes. The W5115 line is the 304 stainless version of the 5115 family, rated 68 kg, the U4510K is a soft-closing 304 stainless variant, and the DQ5115 adds a locking / anti-tip option — a full portfolio for cart and lab furniture.

How does AOLISHENG W5115 compare to HVPAL HA3504?

W5115 is the 304 stainless model rated 68 kg; the A5115 is the standard Q235 base model of the same family. W5115 and HA3504 both use 304-class stainless, with W5115 at 68 kg vs HA3504’s 60 kg — more headroom for fully loaded carts at the same corrosion resistance — and AOLISHENG adds a soft-close (U4510K) and locking (DQ5115) stainless path HVPAL’s single SKU doesn’t cover.

Can medical cart slides be soft-close and locked?

Yes — pair W5115 with the U4510K soft-closing stainless mechanism to prevent slamming, and specify the DQ5115 locking / anti-tip variant so drawers stay shut on carts that move between rooms.
