How to Fit The Tanklok

Fitting your tanklok for the first time should take no more than five minutes. All you need is a drill. Everything else including the drill bit is provided in the Tanklok pack.

1: View tank from above and use marker to place 2 lines opposite each other as indicated above.

2: Ensure there is sufficient access to drill 2 holes for the tanklok shaft where you have marked. Reposition marks if space is restricted. Eg Adjacent walls

3: Now view tank from the side and contine 2 lines down to bottom edge of lid. Place a horizontal mark on side of lid as indicated ensuring that there is sufficient material overlap between the sides of the lid and the access hatch up-stand . Repeat on other side. These are the centre marks for drill hole.

5: Slide Tanklock shaft through holes and complete the assembly as indicated above.

  1. I see that your tanklok is no longer available. Will it be coming back into stock? If not, do you know where I could get one?

    1. Hi Graine,
      We tried to order from supplier about 6 weeks ago and we were told they have no stock and have no immediate intention of getting more produced. We do have a great tank lock from spinsecure. This has the added advantage of not needing a padlock. Padlocks can tend to seize up when exposed to the outdoor elements meaning you might eventually need to break lock to access your oil tank to refill.
