Installing heavy duty drawer slides the right way is one of the most important steps in building a stable, smooth, and long-lasting storage system. Whether you're upgrading a work van, building a truck bed drawer system, setting up an RV kitchen, or constructing industrial tool cabinets, proper installation ensures that your drawer won’t sag, jam, or fail under load.
This guide explains how to install heavy duty drawer slides, specifically the 76mm double-track heavy duty drawer slides from AOLISHENG—our strongest, smoothest, and most stable runners designed for demanding applications.
We cover both DIY home builders and professional contractors, with clear steps, mounting options, common mistakes, and best practices for achieving a reliable setup.
1. Why 76mm Heavy Duty Drawer Slides Are Different
Before installation, it helps to understand what makes these heavy duty drawer slides unique.
AOLISHENG 76mm slides are:

-
Made from 2.5mm cold-rolled steel for greater rigidity
-
Rated for up to 660 lb (300 kg) depending on length
-
Available in side-mount heavy duty slides configurations
These characteristics make them ideal for:
-
Truck bed drawer slides (full extension outdoor use)
-
Van conversion drawer slides for tool and camping storage
-
RV drawer slides for kitchen systems and fridge pull-outs
-
Outdoor kitchen slides
-
Heavy duty fridge slides
-
Tool drawer slides
-
Industrial drawer slides
When strength, stability, and smooth travel matter, 76mm heavy duty runners outperform standard slides.

Pro tip for professionals:
✔ Use threaded inserts or rivnuts for industrial metal drawers.
✔ For vans/trucks, use T-nuts or countersunk bolts to anchor into plywood platforms.
3. Side Mount vs Bottom Mount — Which Should You Use?
Most wide heavy duty drawer slides—especially 76mm double-track models—are designed for side mounting. This provides maximum weight capacity and the strongest structural support.
Side Mount (Recommended)
-
Supports the full rated load
-
Best for van, truck, RV, and industrial use
-
Maximum stability
-
Works perfectly with double-track slides
-
Ideal for 660 lb drawer slides installation
Bottom Mount
Not recommended for heavy duty loads, but occasionally used for:
-
Lightweight kitchen drawers
-
Decorative furniture
-
Non-load-bearing applications
For all van conversion, truck bed systems, tool drawers, and industrial cabinets, always choose side mount heavy duty slides.
4. Step-by-Step: How to Install Heavy Duty Drawer Slides (Side Mount)
Step 1 — Measure Your Space
Measure:
-
Cabinet opening width
-
Drawer width
-
Slide length
-
Installation clearance
AOLISHENG 76mm heavy duty drawer slides require:
-
39.2 mm (1.54 in) clearance per side
-
Slide length = drawer depth or 1–2 inches shorter
For truck bed drawers and van platforms, verify you have enough room for full extension installation.
Step 2 — Remove the Inner Rail
Pull the slide to full extension.
Locate the black disconnect lever.
Press it and slide the inner rail out.
This rail attaches to your drawer.
The outer rail stays on the cabinet or platform.
Step 3 — Install the Outer Rail (Cabinet / Platform Side)
-
Hold the outer rail level against the cabinet or drawer frame
-
Align it with your marked centerline
-
Drill pilot holes
-
Secure with heavy duty screws
-
Check level at least twice
Tip for van conversion and truck builds:
✔ Add 1–2 mm shims if your plywood platform isn’t perfectly flat.
✔ For industrial drawer slides, ensure the metal frame is square.
Step 4 — Attach the Inner Rail to the Drawer
-
Align the rail flush and parallel to the bottom edge
-
Mark hole locations
-
Drill and fasten securely
-
Double-check the rail is perfectly level
If the inner rail tilts even slightly, the drawer will jam under heavy load.
Step 5 — Insert the Drawer and Lock the Rails Together
Slide the drawer straight into the cabinet.
You’ll hear a click when the ball bearings engage the inner rail.
Test:
✔ Smooth travel
✔ No rubbing or scratching
✔ No sagging
✔ Full extension works properly
If anything feels uneven, adjust the screw positions.
5. Common Installation Mistakes (and How to Avoid Them)
❌ 1. Cabinet and drawer not square
→ Heavy duty drawer runners require precision.
❌ 2. Using wrong screws
→ Weak screws can shear under load.
❌ 3. Mounting on thin plywood
→ Reinforce with 3/4" (18mm) plywood or steel brackets.
❌ 4. Installing slides too high/low
→ Must align perfectly on both sides.
❌ 5. Not allowing enough clearance
→ Measure twice before drilling.
