  • What are Lift the Dot fasteners and how to fit

    Lift the Dot

    Intro

    Lift the dot fasteners were first invented to hold curtains back on horse drawn carriages. They then moved into the military industry used for keeping satchels bags closed and also gun holsters shut. Due to their strength and durability they elevated onto the marine and automotive market. Lift the dots are unique as they are locked on three sides and can only be opened by "lifting the dot" on one side. This is always marked with a dot on the socket. The prongs on the socket come in two lengths to accommodate different thickness of material. There are many types of studs also, again to entertain the thickness of material or the material they are being fixed too. Lift the dot fasteners are now used on a wide range of things including classic car hoods, military satchels, marine covers, boat canopies, vintage pram covers, narrowboat cratch cover, pram hoods and we even had a cattery purchase quite a few to be used for attaching cat hammocks to scratching posts.

    Types of lift the dot fasteners

    Full range of lift the dot fasteners

     

    Lift the dot socket and plateThe lift the dot socket and plate. The two parts that attach to your canopy. Make sure to fit the socket the correct way up as you can only pull the fastener off from the marked DOT end. I tend to only sell the genuine DOT brand lift the dots. They have been around for years and used by 99% of canopy designers today.  

    Lift the dot socket and plate with long prongsIf your canvas / awning is slightly thicker than normal you can opted for the lift the dot socket and plate with longer prongs. This allows for multiple layers of canvas. 

    The prongs push through the canvas and into the plate on the other side where the prongs are then folded against the plate to hold in place.  


    Lift the dot clinch stud and washer for canvas to canvasThe lift the dot 2 prong stud and clinch plate are used when you want to attach a piece of canvas to another piece of canvas. No hole is needed to be cut either , just two slits in the material so the two prongs can be inserted through the canvas and into the washer on the other side. A very useful little fastener type. 

    Lift the dot short thread stud self taping woodscrewI have quite a few types of studs with self taping threads, threaded studs and nuts and machine threaded studs. The self taping short and long thread studs would be the most common. Although they are called self tap, you still need to drill a pilot hole and if fitting to gel coat I would advise on countersinking the hole because the gel coat could crack when tightening the stud.Lift the dot self tap long thread stud woodscrew So why chose the short or long then?? Its simple, some boats and classic cars have thin walls, so if you dont want a sharp point coming through the inside then use the short thread. They are both rigid and the short thread has enough thread to make it a good firm base. 

     

    Lift the dot 2 hole base stud screw down fastenerNext we have the 2 hole base studs. It's really down to personal preference if you prefer to use this stud or the self taping. Sometimes these ones are more easily removed or you can also fit whatever screw, nut or bolt you prefer through the holes. 

     

    Lift the dot 2 hole base with longer head stud fastenerThe lift the dot 2 hole base fastener comes in different sizes. The most common is the one above but if you maybe need to fit a thicker canvas over the stud by using the long prong socket or need to fit more than 1 socket and plate to the stud then this is the one to go for. It also has a thicker base as it usually would end up taking more strain.

    Lift the dot double height self tap machine threaded studAnother way to have two sockets on the one stud is to use the machine threaded self taping stud. again it will require a pilot hole drilled. This stud is very robust and the thread is slightly thicker than the two self tap above. All my lift the dots are compatible with each other.

     


    Lift the dot threaded stud and nut m5 x 10mmThe last studs to introduce you to are the threaded studs and nuts. These are great if you have access to the other side of the boat wall/deck or for car body work and materials that may not hold a self tap stud. Simply drill out a hole and fasten these studs and nuts.

    Lift the dot hole punch tool

    But just before you go, here we have the lift the dot hole punch tool. With the aid of a hammer and using a striking action you can pre cut the hole and four slits needed in your fabric to make fitting the socket a much easier job.

    If you have read the different types of lift the dot fasteners in part 1 you will be aware of their many functions and sizes. 

    Here I am going to describe how the socket and plate are fitted to a section of canvas. 

     


    How to fit lift the dot fastenerI am just using a few pieces of canvas cuttings for these fitting guides. Makes it easier to see each process.  

         
          

    How to fit lift the dot fasteners with lift the dot toolSo here we have the lift the dot socket and plate. Also our lift the dot hole punch which will come in very handy.
    The first thing to point out is the positioning of the socket. As you can only unlock these fasteners by lifting the dot. So you want to have it sitting with the dot along the edge of the material. (I am using a small section of canvas so it wont matter)

    How to fit lift the dot fasteners with lift the dot toolUsually the studs will already be in place so you should pull the canvas over your stud and mark where you feel the stud should come through your canvas. This will be where you place the hole part of the cutter, but make sure you have the cutter the correct way around as the 4 prongs are not evenly spread. They have 2 closer to the DOT and the other 2 are further apart. 


    How to fit lift the dot fasteners with lift the dot toolNow place a soft piece of wood under the canvas and strike the tool with a hammer. You may have to hit several times under you get this four slits and a nice cut hole in your canvas.
    So in this instance the fasteners dot part will be at the bottom (I spun the tool 90 degrees from the picture above)

      Is it possible to change a popper fastener on a pram apron to a lift the dot fastening? Would the hole left when I remove the popper be in the correct place for the lift the dot hole to line up with its retainer? Info would be appreciated as I’m holding off buying until I know the process would work. The retainers are attached to the pram so could you supply the correct size lift the dot fastener for a Wilson Silver Shadow coachbuilt pram?

      Thanks
