Teleflex Window Winding Gear Systems

Teleflex window winding gear systems can operate single or multiple high-level windows by using a remote handle at low level.

Often referred to as Teleflex winders which is an old brand name, there are actually several brands available such as Highline and Ultraflex Control Systems (UCS) amongst the most popular options.

Let us help you choose!

All these systems look very similar in design, and work on the same principles, many of the parts are interchangeable so call us for advice.

Manual Teleflex window winding gears can be fitted to most types of windows:

  • Side hung
  • Top hung
  • Bottom Hung Open in or Out
  • Skylight and Roof Windows

Manual winding window gears are extremely versatile and make a suitable, cost-effective solution for both commercial and domestic applications. These types of manual openers are widely used in schools, hospitals, offices and commercial buildings but can be a great alternative options where wiring is not possible.

Installation Examples

Below are some illustrations of popular installation formats.  Note: when referring to these it’s important to note the exit position from the operator and the orientation of the chain cases on the vent units.

Manual Winding Gear Single Vent Illustration

Single, top hung vent

The simplest installation option, a single window with one or more openers depending on the width of the vent.

Manual Winding Gear Multiple Vents with Junction

Multiple banks with junction box

Here there are multiple banks of windows driven by a single operator. A junction is used to provide 3 different conduit paths from the operator’s 2 exits, avoiding the need to extend a conduit run from one bank to another.

Manual Winding Gear Bottom Hung Vent Banks

Bottom Hung example

Manual winding gear is also suitable for other window types such as bottom hung, or side hung.

Designing a Manual Winding Gear System?

There are several ways you can fit your manual openers, and we are experienced in working out the best configuration for your needs.

Most systems are straightforward and simple to specify, but we will always make sure we talk to you about your situation and consider the following.

  • The size and weight of your opening vents
  • How high up your windows are
  • How far you want to open your vent, chain openers come in 250mm or 380mm opening options (the opening distance will depend on the size of your window as well)
  • What your window is made from, uPVC, timber, aluminium, metal crittall window or skylight window. There is a choice of brackets available for different frames
  • How your windows are hinged, i.e. top hung, side hung, centre pivot etc
  • The number of opening vents in a bank you want to operate together (The load)
  • The number bends in the conduit required to reach your window (Friction is created with each bend)
  • The distance the cable travels from the operator the last chain in the run

Quoting is straight forward and requires just a few answers to some key questions like the ones listed above to help configurate exactly what it is you need.

For example, operating a typical group of windows would be a midi operator (handle) at low level opening 1 to 4 windows in a group and would not need any special considerations.

If you were looking to open a large number of high-level windows in a bank you may need to opt for a more powerful operating handle such as a Maxi operator as these can push with more force. But we have the experience to work out what you need.

Frequently Asked Questions

Can you use Manual Winding Gear (Teleflex) on bottom hung, open in windows?2023-06-02T14:24:28+01:00

Yes, these window types are also known as hopper windows. We can supply the necessary brackets and fixings to make an opener work on these.

What lengths do you supply the conduit in?2023-07-03T08:37:13+01:00

The conduit comes in 3m lengths which can be joined together to form longer lengths. When joining conduit you will need to use our conduit grooving tool to ensure the two ends are securely connected.

As well as the common White, Grey, and Black options, Rocburn are able to supply Anthrocite Grey from stock as well.

My manual winding gear systems has failed, should I repair or replace the system?2023-07-03T08:39:06+01:00

Typically speaking it’s best to replace the system, for a couple of reasons.  First is that although Teleflex is the best known, there are multiple brands in the market manufacturing winding gear and there’s no easy way to tell which brand conduit or cable you have. Another key reason is that all the equipment is subject to the same wear and tear, therefore, other components are likely to fail very soon.

How do Teleflex and other Manual Winding Gear Systems work?2023-07-03T08:40:36+01:00

By turning the operating handle from an accessible location, you drive a helical cable inside a conduit fixed to your wall. As the cable travels through a chain opener located at the window, it drives a cog which then drives a chain out of the opener body and its links lock in a way that allows the chain to become rigid, pushing the window or vent open.
