A slide with self-close will close the slide by engaging the mechanism in the rear of the cabinet member using a pin element on the drawer member. The closing action is very positive and is performed by a spring that has no damping.
Slides can have different closing forces to pull in different loads. The mechanism also acts as a hold-in, by virtue of the spring pressure holding the slide closed – preventing the slide from bouncing open.
Because the mechanism requires a spring force to pull the load closed, this will also affect the opening force; the spring rate needs to be overcome while opening the drawer. Let’s image a self-close slide on a drawer. The user will feel a resistance from the spring while opening the drawer, but this will disappear once the slide has been released from the spring.
This helps prevent the slide from slamming closed. The damper is normally positioned in the mechanism at the rear of the slide, similar to the self-close, and controls the closing action.
This mechanism also acts as a hold-in, stopping the slide from bouncing open. Because the mechanism requires a spring force to pull the load closed, it will also affect the opening force.
But, it is not locked in this position. To overcome the hold you need to provide an additional force to the slide, by pushing firmly, and it will overcome the feature and move inward.
This is a useful feature for slides used on keyboard shelves, for example.
A lock out feature on a slide will be a physical lever or latch that has to be operated before the slide will move. For example, the 9308 has a lever at the front end and the 0305 has a push latch toward the centre of the slide mechanism.
Slides with lock-out are more usually used to support equipment that needs to be held fully open and static during maintenance, for example.

1. Is a ball bearing slide the best option? If you have a restricted budget or just need a simple movement carrying very little weight, then don’t forget to look into roller slides or simple friction systems
2. Slides are categorised by load rating so think carefully about the weight that you expect the slide to carry. Remember to add the weight of all the elements to be moved, including the construction materials, into your calculations. This will give you a good starting point to understand the size of slide you need.
3. How far do you need the item to move? This will give you the slide travel or extension. This is the difference in length between a closed and fully opened slide. Slides come in various extensions - part extension, full extension, over travel, linear.
4. How much space do you have to accommodate the slide? Each type of slide has its own side space requirement, but you need to also take into account the profile height of the slide.
5. How far apart will the slides be positioned and will they be side or flat mounted? Slides are typically tested for their catalogue load ratings at 450mm apart and some slides cannot be flat mounted. Those slides that can be flat mounted will have a reduced load rating.
6. What finish do you need? Zinc plated steel is standard, but we also do black, white, stainless steel, aluminium and corrosion resistant coatings.
7. Think about mounting options. How do you want to fix the slide into the application? The majority of slides have screw fixing hole patterns, but there are also slides with bayonet mounting options for fixing into steel cabinets. Or use our ladder strip mounting to allow bayonet slides to be mounted into wooden cabinets.
8. Does the application need a particular function? This will make you think about the additional features that you may need in or around the slide. There are a number of common options such as, detent hold in, disconnect, self close, easy close, lock in, lock out, etc.
9. You can use our slide selector tool on the website to configure a product. You can also save slides to your own Product library to compare features.
10. Can’t see the slide you need? Then ask for help. We are happy to receive your application photos or drawings and give advice. Email your question to [email protected]

Accuride’s distribution network covers all of Europe and employs well over 1,000 sales representatives on our behalf. We want our customers to buy the correct slide for their project, so keeping our distributors up to date with our products is vital. They need to be able to understand our products and be able to specify them into a huge variety of markets and applications.
One-off training just won’t do. We are always introducing new products and discovering new markets so we need to be training continually.
We make certain that our distributors are experts on our product line and that the end customers have full confidence in them.
It is not only front line sales who need in-depth knowledge about Accuride and our products. The distributor telesales and customer services staff are also included in training sessions.
Accuride’s regional sales managers all take direct responsibility for training their own distributors. This strengthens the relationships between the staff on both sides. We will go to their premises and organise hands-on training, which will be tailored depending on the expertise and job function of the group.
The follow can be applied to most product training. I hope that you find it helpful.
Although slide shows can be useful, don’t be a slave to the screen.
Your audience cannot listen to you, look at a sample and read the slide at the same time. Add blank slides where you think you may stop to look at samples or discuss an issue or invite examples from the floor. PowerPoint is ideal for showing pictures and creating a lesson structure, but can also be boring for an audience.
Consider using flip charts for more interactive sessions.
Use case studies from their experiences. You may find that they already have some problems or queries that you can use in class as a group discussion to find the solution.
You can also make some up to illustrate particular points and introduce role playing if you think that it will be useful and welcome. Have some case studies or application problems ready for the class to discuss.
Be clear, precise and get confirmation that each point has been understood by the group. If the session is a series of building blocks then ensure that each block is understood before moving on. Use questioning, discussion, case studies and working examples to check understanding.
Questioning is the most usual way of checking on understanding. An ‘open’ question calls for an answer which draws on experience, knowledge and judgement – often beyond the confines of the class.
When training, you need to get the audience interested and involved, so make sure that you use every opportunity to get their opinion or experience by using conversation starters or open questions.
Be sure that you know why you are asking questions (does the question meet the lesson objective?), know the answers, be sure that the students’ ideas will not be dismissed and that you can control any ensuing discussions.
You may wish to use a questionnaire to find out if your audience has found your training useful.
1. Understand your audience
Assess your audience; group size, interest and level of knowledge. Agree with your customer beforehand what result(s) you need to achieve at the end of the session.
2. Prepare the content
Structure the key messages, pulling together the relevant information. Decide on the correct visual aids, hand-outs and demo units to put across the information.
3. Create the right environment
Get the location right and be well prepared to present in that location.
4. Work on your performance
Identify what your personal style/strengths are. Understand how to build rapport with your audience. Work on voice projection and handling questions.

This product has proved to have many different types of applications, so we asked our engineering department for a couple of options depending on the panel thickness.
