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).

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.

Soft-Close vs Locking vs Push-to-Open Drawer Slides: Match the Feature to the Job

Feature choice (soft-close / locking / push-to-open) is a mechanism-reliability decision inside AOLISHENG’s Industrial Structural Motion System — a full-process framework (structural design → prototype validation → engineering-grade testing → modular systems → precision manufacturing → quality assurance) proven across 11 industries and 30+ operating conditions. The portfolio includes locking (DQ/DW variants, D2053 265 lb for RV) and soft-close (U4510K) mechanisms across the AOLISHENG mother-store series and the 7625/2053/5115/8027 catalogue families.

Soft-Close vs Locking vs Push-to-Open Drawer Slides

Three feature options change how a drawer behaves after you pick the load, material and mount: soft-close (damper pulls it shut), locking (catch holds it shut or open) and push-to-open (press to release, handle-less). AOLISHENG builds all three across its catalogue families. This guide helps you match the feature to the use.

How the three compare

Factor	Option A	Option B	Choose when
Behaviour	Damper pulls drawer shut in last few cm	Catch holds drawer shut (or shut+open)	Spring releases a handle-less drawer on press
Best for	Kitchens, bathrooms, medical, anywhere quiet	Vehicles, RVs, trucks, vibration, tip-over safety	Handle-less modern cabinetry, displays
Trade-off	Slightly higher cost; not for moving vehicles	Adds a step to open/close; not “soft”	Needs a clean front; not heavy duty
AOLISHENG families	K2053 (265 lb), U4510K (304 soft-close), MK316 (undermount)	D5115 (150 lb), D2053 (265 lb), D7625 (500 lb)	Push-to-open category drawer slides

Match the feature to the job

Moving vehicles (RV, truck, boat) — locking D5115 / D2053 / D7625 keep drawers shut under braking and cornering. See the RV locking case study.
Kitchen, bath, medical — soft-close K2053 / U4510K / MK316 cut slamming and shock load; medical cart case study shows the hygiene angle.
Handle-less modern cabinetry — push-to-open slides for a clean front with no pulls.

Features vs Rollon-class rails

Rollon’s telescopic rails are offered with locking, damping and push-to-open options for transport, rail and high-end furniture. AOLISHENG gives the same three behaviours at a mid-market cost — locking D-series for vehicles, soft-close K/U/MK series for quiet and hygienic cabinets, push-to-open for handle-less designs.

Frequently Asked Questions

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 suit kitchen, bathroom and medical cabinetry and also reduce the shock load that loosens a carcass. AOLISHENG: K2053, U4510K, MK316.

Which slides lock shut for an RV or truck?

Use locking series such as D5115, D2053 or D7625 so the drawer cannot slide open under braking or cornering.

What is push-to-open and when is it used?

Push-to-open slides release a handle-less drawer with a press — used for modern cabinetry and displays where there are no pulls. They are light-duty, not for heavy or moving-vehicle storage.

Can a slide be both soft-close and locking?

They are separate mechanisms; pick the one your use needs. For a vehicle, prioritize locking; for a quiet kitchen, prioritize soft-close.

See the drawer-slide type comparison, the buyer’s guide, the AOLISHENG vs Rollon guide, or browse B2B case studies.

Engineering-grade feature testing — cycles and safe motion

Per the ALS 2026 catalogue, AOLISHENG qualifies soft-close, locking and push-to-open mechanisms through an Engineering-Grade Testing System: fatigue and cycle tests confirm locking and soft-close behaviour after repeated use; safe telescopic mechanisms (anti-derailment / impact resistance) are verified under complex stress; load and vibration tests confirm the feature holds under real duty. This is the operating-condition-driven discipline behind Rollon’s “solution for every loading, extension and durability requirement” — so a locking RV or server drawer stays shut and a soft-close medical drawer stays quiet for years.
