Packed: 1
- Designed to provide a clear airflow passage to a void beneath an insulated suspended floor - 8,000mm² airflow
- Current and future requirements of Part L of the Building Regulations along with other standards and regulations have led to an increase in the depth of thermal insulation in suspended floors along with an increase in cavity widths to accommodate greater amounts of cavity wall insulation
- This has meant that clear access to an underfloor void may be as far as 6 or 7 brick courses (525mm) below the level of an airbrick and potentially as much as 350mm from the outer face of the external leaf - traditional telescopic underfloor ventilators would not be able to achieve this without the use of additional vertical and horizontal extension sleeves
- The dual extended underfloor vent offers vertical telescopic adjustment of between 5 and 8 brick courses (318mm-575mm) without the need for an extension sleeve
- The horizontal outlet is long enough to bridge through an overall wall thickness of 350mm without the need for an additional extension
- The front aperture is designed for use with a combination airbrick or it can be used in conjunction with a traditional clay airbrick, although this would reduce the overall airflow through the system
- Regulations - BRE Digest 17, BRE Digest 262, Building Regulations C4, NHBC Standards 5.2 and BS 5250:2011 Control of Condensation in Building

An average table support.
These table legs are made of "jointed", threaded, 3/4inch steel pipes and it is imperative that they are assembled correctly and evenly; if not, the table will be wobbly and unstable. Need to ensure that the joints are fully tight. The assembly instructions are vague, so you may face some frustration during assembly if you're not too mechanically inclined. It is possible to modify the design of the legs to meet your specific needs, but you may need to purchase additional 3/4 inch piping and couplings at your local plumbing store. Good luck!

Easy to put together
Great! We had to buy extensions because I wanted a higher table but it worked great.
