Universal Decking Connector
Our Universal Decking Connectors are a simple and effective concealed fixing system for installing deck boards, where hidden fixings are preferred. The connectors are screwed to the bottom of the boards and then screwed to the joists, so there are no fixings through the face of the boards.
Universal Decking Connectors are made from 304 grade stainless steel. They are available either uncoated (stainless steel finish) or stainless steel coated in a black finish, which makes them slightly less visible through the gap between the boards. Stainless steel screws are included, along with a suitable driver bit.
Universal Decking Connectors are screwed to the back of the deck boards. It may help if you go through the boards and mark the side you will be using as the back with pencil or chalk.
1.) Cut the first deck board to length then lay it across the joists in the exact position that it will be installed. Then mark the position of the centre of each joist on the deck board.
2.) With the underside of the board facing upwards draw a pencil line across the width of the board to mark each joist centre. These pencil lines mark the position to attach the connectors.
3.) With the pencil lines as a guide, attach the connectors to the underside of the deck board using the stainless steel blank screws (UNIA 4,2 x 17mm or 22mm). The connector which will slide underneath the previous board should be 2 – 3 cm away from the side of the substructure. The second connector which will be mounted to the joist using the black stainless steel screw (UNIA 4,2 x 35 mm) should be mounted central to the guideline as illustrated in the picture 3. At this stage the connectors are upside down. Note that the first and last deck boards need to be fixed through the face of the boards on the outside edge. A connector is still required to create the correct gap between the joist and the underside of the deck board. These are installed perpendicular to the rest of the connectors as illustrated below picture 7. You will need to hammer down the lip on the connectors to do this.
4.) Attach the connectors to the deck board using UNIA 4,2 x 17mm or 22mm screws as explained above.
5.) Turn the board over and slide the floating connectors underneath the previous board and fix the other connector using UNIA 4,2 x 35 mm to the joist.
6.) Continue this procedure until all the deck boards have been installed.
7.) Picture 7 illustrates our deck board installation aid which enables the installer to create uniform gaps between the deck boards throughout the installation process (not included – please order separately).
8.) Picture 8 Illustrates the connector being fixed to the substructure once the desired board joint has been chosen.
The illustrations below picture 7 and 8 show how to install the first and last board. Please follow the procedure on the left side. The outside edge of the board has to be visibly fastened but we still need a connector on this edge for the distance between the bottom of the board and the top of the substructure (7 mm). Simply mount the connector upside down to the top of the substructure. Mount the connector which will be fixed to the substructure as normal. Turn the board over pre-drill and countersink the outside edge and fix using a screw.
The last picture illustrates the maximum distances between all components.

Economy Delivery Service
Our economy delivery service uses our own delivery vehicles and is available in selected postcode areas only. Orders are grouped with others within specific regions and scheduled accordingly. This allows us to provide a significantly lower delivery rate. We endeavour to despatch your order as quickly as possible, however the date can vary depending on other orders in your area, up to a maximum of 14 days. Feel free to contact our customer support team on T: 0151 541 5485 for an estimated delivery date prior to ordering.
Standard Delivery Service
If you require your order urgently we are able to deliver via an independent haulier within 5-7 working days (factory coated orders may take a little longer). Once your order has been placed online, a member of our customer support team will contact you by phone to arrange a convenient delivery day and discuss your requirements. Deliveries usually take place between Monday & Friday between 8am and 6pm.
Specialist Delivery Service
Deliveries to Northern Ireland, Orkney Islands, Argyll & Bute, Isle of Wight, the Isle of Man and Shetland Islands use our specialist delivery service. Delivery charges are calculated by the number of pallet spaces taken up by the load.
A pallet space is 1.22 metres or part thereof. The number of pallet spaces taken is determined by the longest item on the order. For example, if you order 2.44 metre long deck boards you will be charged for 2 pallet spaces.
Deliveries using this service usually take place 3 - 5 days after we receive your order (factory coated orders may take a little longer). We will contact you by phone to arrange a convenient delivery day. Deliveries usually take place Monday to Friday between 8am and 6pm.
Saturday Delivery Service
A Saturday delivery service is available on request and subject to availability (additional charges will apply). Please contact our customer support team on T: 0151 541 5485 for a quote.
Courier Delivery Service
Smaller items like screws or wood finish are delivered using a reliable express parcel service. Our standard leadtime for this service is 2-3 days. Next working day delivery is also available on smaller items ordered before 11am.
Although rare, an additional charge may be payable should the delivery company require to attempt more than two deliveries of the same order.
Deliveries are often made on large vehicles. Please let us know in advance if there are any access restrictions; for example narrow streets / farm tracks, parking restrictions, road works etc which may affect delivery. Failure to notify us, in advance, of any access restrictions may result in additional delivery charges and / or an inability to fulfil the delivery.
When Your Delivery Arrives
To keep delivery charges to a minimum, goods are manually offloaded from the delivery vehicle. Someone must be on-site to sign for the delivery and to assist with the offload. If your order contains large lengths of timber you may need additional people on hand to help. As with most companies delivering building materials, delivery obligation ends at the kerbside.
If you would prefer to arrange your own haulage or collect in person please let us know. Collection is from either our Widnes (Cheshire) or Harmondsworth (W. London) branch. We can schedule in your collection so that your goods are picked and packed in advance and our warehouse team can assist in loading your vehicle promptly.
As orders may need to be processed, picked and packed from multiple locations we are unfortunately unable to offer a 'Click & Collect' service.
Customers will be contacted to arrange a convenient date and time for collection.
