Frequently Asked Questions

The word ‘Trellidor’ is actually the brand name of South African security barrier manufacturer Trellidor. The company manufactures steel and aluminium sliding trellis-style safety gates. These are fitted to doors and windows to protect people from intruders.
  • Double uprights. ‘Uprights’ are the vertical steel bars that run from the top to bottom track, and you’ll see them in pairs along the length of a Trellidor security gate. This is a strengthening feature.
  • The links that form part of the trellis pattern across a Trellidor gate link three uprights together.
  • U-shaped profiles. The vertical steel bars and the links that connect them are shaped into a ‘U’, making it easy to coat all surfaces against corrosion.
  • The unique, patented Trellidor lock is branded. The name ‘Trellidor’ is etched into the lock cylinder.
  • Trellidor gates have a single key and keyhole.
  • Trellidor gates have a T-shaped, low profile bottom track, designed to reduce the chances of tripping over the track and also to make it harder for criminals to pull the uprights off the track.
Custom-made sliding gates fitted by an expert technician instead give you far better protection. Rather contact a Trellidor franchise near you for gates that are fitted with tamper-proof fixings and the locks are designed to make it difficult for robbers to breakthrough.
  • Use a premium quality (salt-free) car wash liquid, mixed with water as per manufacturer’s directions and a soft cotton cloth to clean the entire unit.
  • Hard to reach areas may require the use of a soft nylon bristle brush such as a dishwashing brush.
  • Dry the unit with a soft cotton cloth or chamois.
  • Apply the Trellidor lubricating spray (available from your local franchise) to all moving parts, especially all hinge points inside the channel sections and into the top tracks.
  • Shake the can of lubricating spray well, apply to a clean cotton cloth and wipe the entire unit, or spray directly onto unit from a distance of about 20cm.
  • Wipe off the excess residue. This will form a protective barrier against both moisture and contamination of airborne pollutants.
  • A second application may be required if the unit has stood for too long without being lubricated and has become stiff, dry and difficult to operate.

Take special note of the following warnings:

Never use abrasive cleaners, detergent-based cleaners or solvent-based cleaners such as scouring agents, dishwashing liquids, washing powders, thinners etc as these could adversely affect the expected life of the sliding security gate.
Do not spray into the keyhole of the cylinder where the key fits!
Remember to read the warnings on the lubricating spray label as the product is highly flammable, must not be ingested and is irritating to eyes and skin.

Trellidor locks are patented designs that are fitted using specialist tools. These tools are not easily available at hardware stores, which is one of the safety features built into Trellidor gates.

You may need to change your lock under the following circumstances:

  • You’ve had an attempted break-in and the lock has been damaged.
  • If you have several sliding gates in your home, you may want to get your gates keyed-alike. This means that all your locks can be opened with the same key, instead of using different keys for each gate. Trellidor offers this option so that you don’t have to keep large bunches of keys around the home. The locks will have to be changed to do this.
  • If you’ve had a break-in it is advisable to change the locks. The home invaders may steal your keys and use them to get in again.
  • The same applies if you have dismissed employees that work at your home.
  • If you have moved into a new home that has sliding security gates, get the original manufacturer to change the locks. You never know who may have had access to the sliding gate keys.
  • If you keep your house keys on the same key ring as your car keys and have been hijacked. Change the sliding security gate locks to avoid the hijackers or accomplices breaking into your home.

In all these cases, you need to call in your local authorised Trellidor supplier to replace the locks for you. They will do it quickly and easily as they have the correct tools to do so.
