Are the prices per pair?

Yes the prices you see are for a pair of hinges i.e. one window.

How easy is it to replace a hinge?

Once you know the correct sizes and type of hinge you require (all information available on the web page) the whole replacement can be done in ten minutes or less. However, always have a second person available to help with the weight of the window.

What is the difference between the H01 black cap and the H06 grey cap?

The black and the grey caps are usually good indicators as to the manufacturer of the hinge you are replacing, although some don't have end caps. This means there is more likelihood the fixing screws will all line but we advise you to check the diagrams to be sure. You can use either though really as the first hole on both the frame and the opener are usually in the same place and if the rest aren't you can always re-spot them with a small drill.

My frames are aluminium and the hinges are held with rivets not screws?

This is a fairly typical method for attaching hinges to aluminium frames. The reason why it is done this way is that the frames are very thin (less than 2mm) and this is not sufficient to form a screw thread that would hold the weight of the window. You must re-fix using rivets in that case and if in doubt consult a double glazing repairs company local to you for help. Rivets are identified by a small hole in the centre of what looks like a screw head and to remove them you need to drill the heads off.

What do I need to know in order to replace a hinge on my window?

In the first instance you need to select the hinge you would like to fit. If you use the prompts on the relevant web page it will tell you what you need to know for each hinge and through the pop-up’s you can see the diagrams you need to make the correct selections. Everything you require will be sent with the hinge including a guide to check and set the hinge depth correctly.

I have received a pair of hinges but they open the same way?

The hinges are sold in pairs so one pair for each window. Each of those individual hinges will be marked up with an arrow or a left/right marking. The pair should have two hinges with arrows going in opposite directions. You need to open the hinges in the direction of the arrow only. If you open it the other way the end of the hinge will not go back into the corner of the cap and the window will not close correctly. You will need to take this off the window if that is the case and then pop the hinge back into place in the palm of your hand and then open it the correct way. The arrow direction also determines which side of the window you fix each of the hinges to. So when the hinge is fixed to the window the arrow should point in the direction of the opening direction as well.

If it is the first time you have used these hinges then these are typical problems but you can correct them if you follow the advice given above.

What tips would you give me when installing the new hinges?

Always have two people available that are capable of holding the weight of the window. Do not underestimate how heavy a double glazed window really is.
When fitting the H02, H03 or H04 hinges, ensure that the hinges are opened in the direction of the arrow only. This corresponds to the direction of the window opening and ensures that you have the hinge on the correct side of the window. 
Make sure that the first fixing hole in the corner lines up on the new hinge and the window otherwise the window will be out of line (generally standard size).
When the opening window is removed drop it onto your bathroom scales and check its weight corresponds with the weights given on this website, or the instruction sheet supplied, for your hinge. If you have triple glazing these hinges will not be strong enough to carry the weight. Check with Technical Support.
Have some repair screws handy.
 
Can these hinges be fitted to other types of frames other than UPVC?

They can be fitted to timber and aluminium windows with friction scissor hinges already in place. Traditional timber windows with butt hinges will not accept these type of hinges without modification to the opening window. Aluminium windows with friction hinges are usually held in place by rivets.

What is a standard hinge?

This is the most common hinge that simply opens your window. Most standard hinges are known as easy clean and this relates to the action of the hinge i.e. the opener comes across the window creating a gap that allows you to reach the outside of the window.

Can I fit restricted hinges in place of a standard hinge?

Yes you can provided the track width is 18mm wide and the length of hinge is available.
Please note that side hung window hinges have one restrictor on the bottom hinge and top hung windows have restricted hinges on each side of the window. The latter is important for safety reasons should someone fall against the window (please be aware that some websites sell only one restricted hinge per pair on a top hung window and this is an extremely dangerous practice with a top hung window).

What screws should I use to fix the hinges to the frames? 

We recommend that you use the existing screws as these should be the correct pitch and length to re-tighten. If the screw thread will not tighten it is possible to use repairs screws that can be purchased from the website under Accessories. Under no circumstances use a screw from a DIY outlet without the correct specification being observed. The wrong screws can lead to corrosion.

Is there any maintenance required?

When you first install the hinges it is recommended that you put one drop of light-grade lubrication oil onto each hinge point - and always keep the slide track free from dirt and grime.

It is good practice to clean, lubricate and check the tightness of all screws/rivets every twelve months.

How can I improve the security of the hinged side of the window?

Check out the ‘Enhanced Window Security’ brackets under Accessories. These can easily be fitted to the hinged side of the window and significantly reinforce the window security at that side of the opener.
 
What weights are the hinges designed to carry?

Generally speaking if the length of the hinge is replaced with a ‘like for like’ length size on a double glazed residential type window the weight should be OK. However, it is always worth a check when you have taken the opening window out to drop it on a set of bathroom scales for re-assurance. If the weight of the window is greater than the weights given by the manufacturers then seek guidance from Technical Support before commencing with replacement. An instruction sheet showing the weights for each hinge size is supplied.
