Description
30mm Black Knock-In Plastic Glides
The 30mm Black Knock-In Plastic Glide is a simple, economical furniture fitting suitable for sofas, ottomans, bed bases and other furniture requiring a fixed plastic glide.
The knock-in fitting provides a neat contact point beneath the furniture without the additional height or movement of a conventional foot or castor. It is particularly useful for furniture manufacture, routine repairs and replacing worn or missing glides.
Available individually or in boxes of 500, making it suitable for both individual repairs and higher-volume trade use.

Knock-In Furniture Glide
The defining feature of this product is its knock-in fixing.
Rather than screwing into a threaded insert, the glide is fitted into a suitable hole or fixing point within the furniture leg or frame. The Livedale Plastic Furniture Glides range specifically distinguishes knock-in glides from screw-in and socket-mounted alternatives.
Typical applications include:
- Sofas and settees
- Ottomans
- Bed bases
- Upholstered furniture
- Furniture frames
- Low-level furniture
- Furniture manufacture
- Replacement and repair work
For other floor-contact fittings, browse the wider Furniture Glides range.
Low-Cost Alternative to Furniture Feet or Castors
The existing Livedale product description specifically positions these plastic knock-in glides as a low-cost alternative to furniture feet or castors.
Choose a 30mm Knock-In Glide where:
- Furniture does not need to roll
- Additional height is not required
- A discreet black fitting is preferred
- A simple plastic floor contact is suitable
- The furniture is already designed for a knock-in fitting
- An economical replacement is required
Where a visible furniture foot would provide a better finished appearance, browse Wooden Furniture Feet & Legs.
Where the furniture needs to remain mobile, browse Furniture Castors.
Check the Knock-In Fitting Before Ordering
The fixing method is just as important as the 30mm glide size.
Before ordering, check:
- Existing glide size
- Existing fixing type
- Hole or fixing-point dimensions
- Condition of the furniture frame
- Available floor-contact area
- Required finished furniture height
- Floor surface
A screw-in, knock-in or socket-mounted glide may look similar once fitted, but the fittings underneath are completely different.
If you’re unsure which type you require, contact Livedale before ordering.
How to Fit a Knock-In Plastic Glide
The glide should be fitted into a compatible fixing point in the furniture frame.
Before fitting:
- Check the existing hole or mounting point
- Make sure the surrounding timber or furniture frame is sound
- Position the glide straight
- Start the fitting carefully
- Tap it progressively into position
- Avoid driving the glide in at an angle
- Do not use excessive force
- Make sure the glide is fully seated and secure

30mm or 40mm Knock-In Plastic Glide?
Livedale offers knock-in plastic glides in both 30mm and 40mm sizes.
Choose this 30mm version where:
- The existing glide is approximately 30mm
- A more compact contact area is required
- The furniture frame is designed for the smaller fitting
- A discreet glide is preferred
For a larger option, see the 40mm Black Knock-In Plastic Glide.
The larger glide should not automatically be considered better. The replacement needs to match the furniture and existing fixing.
Knock-In or Screw-In Plastic Glide?
The Plastic Furniture Glides range contains both knock-in and screw-in fittings.
Knock-In Glide
Choose this product where the furniture has a suitable knock-in mounting point.
Screw-In Glide
Where the furniture uses a threaded fixing instead, see the 25mm Black Screw-In Plastic Glide or larger 60mm Black Screw-In Plastic Glide.
These use a different fixing system and should not be treated as interchangeable with a knock-in glide.
Looking for a Larger Contact Area?
Where the furniture requires a broader floor-contact point, consider the Black Mushroom Glides & Sockets.
Mushroom glides provide a wider contact surface and use a compatible socket arrangement rather than the simple knock-in fitting used on this product. The wider Livedale category positions mushroom glides specifically where a broader, more stable contact area is required.
For a more decorative version, Chrome Mushroom Glides & Sockets are also available within the same range.
Plastic Glide or Felt Floor Protection?
Plastic glides provide a practical and durable floor-contact point, but the floor surface should also be considered.
For delicate wood, laminate or similar hard flooring, a softer felt surface may be more appropriate.
Browse Felt & Nail Glides for felt nail glides, Domes of Silence and self-adhesive felt pads.
The Livedale Plastic Furniture Glides guidance also recommends considering felt alternatives where furniture is being used on delicate flooring.
Plastic Glide or Wooden Furniture Foot?
This 30mm plastic glide is primarily a functional fitting.
Where furniture appearance or additional height is important, a wooden foot may provide a more suitable solution.
Browse Wooden Furniture Feet & Legs for sofa, chair, footstool and upholstered furniture feet.
Changing from a low-profile glide to a wooden foot will alter the finished furniture height, so check the required dimensions before ordering.
Each or Box of 500
The 30mm Black Knock-In Plastic Glide is available:
- Each
- Box of 500
This makes it suitable for individual repairs as well as professional furniture manufacturers and workshops using glides regularly.
Typical trade users include:
- Furniture manufacturers
- Upholstery workshops
- Sofa manufacturers
- Bed manufacturers
- Furniture repair businesses
- Contract furniture suppliers

Check Before Ordering
Before ordering, check:
- 30mm glide size
- Existing knock-in fitting
- Hole or mounting dimensions
- Condition of the furniture frame
- Required finished furniture height
- Floor surface
- Quantity required
The key difference on this product is 30mm knock-in fitting. A similar plastic glide with an M8 thread or socket fitting will not be a direct replacement.
If you’re unsure which glide is suitable, contact Livedale before ordering.
