Buy more = pay less on sliding door parts
Are you active as a window frame company, maintenance company, installation company, property maintenance company, or sliding door specialist? Then you know how important it is to quickly have the right parts available. At the same time, you want to control your purchasing costs and maintain sufficient margin on repairs and renovations.
That’s why Van Doorn Opening Technologies offers an attractive benefit program on various products: buy more = pay less. On selected items within our range, discounts can be as high as 15%, making it interesting to order multiple parts at once or stock up for future projects.
Whether you work with GU lift-and-slide doors, Aliplast systems, or standard sliding doors equipped with Eland Brandt rollers, we offer attractive volume discounts on frequently used parts.
Why choose buy more = pay less?
When you regularly repair or maintain sliding doors, you often encounter the same parts. Ordering multiple pieces at once offers several advantages:
✔ Lower purchase costs per part
✔ More margin on repair and installation work
✔ Fewer rush orders
✔ Always parts in stock for common repairs
✔ Lower transport costs per project
✔ Discounts up to 15%
For many companies, it proves more cost-effective to keep a small stock of frequently used trolleys, locks, handles, and rollers.

GU lift locks for lift-and-slide doors
A well-functioning lift lock is essential for the operation of a lift-and-slide door. When the lifting mechanism wears out, the door can become hard to operate, lock poorly, or no longer lift correctly.
Van Doorn Opening Technologies supplies original GU lift locks for various door heights and versions.
A commonly used version is:
✔ GU 937 lift lock for door height 1865–2365 mm
✔ Backset 27.5 mm
When replacing older GU systems, it is important to consider the changed transmission of the latest generation GU lift locks. As a result, old and new systems are not always interchangeable.
In many cases, we therefore recommend a complete renovation where both the lift lock and the trolleys are replaced.
GU 937 trolley packages
When a lift-and-slide door runs heavily, jerks when opening, or even starts to sag, worn trolleys are often the cause.
For these situations, we supply complete GU 937 trolley packages with a rebate height of 45 mm.
These renovation sets contain:
✔ Front trolley
✔ Rear trolley
✔ Connecting rod of 8 mm
✔ Three rod guides
By replacing the complete system, the sliding door becomes smooth, stable, and reliable in use again.
For maintenance companies and installers, these sets are among the most used renovation products within the GU range.
Eland Brandt running wheels for standard sliding doors
Not every sliding door uses a complete trolley system. Many standard aluminum sliding doors use separate running wheels.
A popular version within our range is the:
✔ Eland Brandt double adjustable nylon running wheel 32 mm
This version offers various advantages:
✔ Double wheel construction for better weight distribution
✔ Adjustable version for precise adjustment
✔ Less noise during use
✔ Suitable for aluminum bottom rails
✔ Reduces wear on the rail
When sliding doors run heavily or produce a scraping noise, worn running wheels are often the cause of the problem.
For companies that regularly maintain sliding doors, it is therefore interesting to keep these parts in stock as standard.
Aliplast ACVG 110 double trolleys
For Aliplast sliding doors, we supply among others the popular:
✔ Aliplast ACVG 110 double trolley with stainless steel wheels
This high-quality trolley is equipped with two stainless steel running wheels and is designed for smooth and durable operation of the sliding door system.
Advantages of this version:
✔ Very low rolling resistance
✔ High load capacity
✔ Durable stainless steel wheel construction
✔ Suitable for intensive use
✔ Long lifespan
When an Aliplast sliding door moves jerkily, runs heavily, or makes a scraping noise, worn trolleys are often the cause.
More benefits for professional users
For companies that regularly perform maintenance on sliding doors, it can be advantageous to order multiple parts at once. This way, you not only benefit from a lower price per part but also immediately have the right stock for future jobs.
Within our range, volume discounts are available on various product groups that can amount up to 15% discount.
This makes it interesting for:
✔ Frame companies
✔ Installation companies
✔ Maintenance companies
✔ Property maintenance
✔ Sliding door specialists
✔ Locksmiths
✔ Service and repair companies
