BaikeenTri glide Slider,Strong Plastic Tri Glide Slides Adjustable Slide Buckle Strap sliders Adjusters for Backpack Belt Strap

Brilliant, no problems at all.

Useful for the task purchased for. Wish I could have got smaller pack though.

Perfect size.

Worked perfectly for the job and a good price.

Nice buckles for my webbing straps

Seen these go for about 4 quid on ebay for a pack of 20 or around 12-25 p a peice on certain sites

I fitted these to my ResMed F20 mask as the Velcro was no longer working.I thought i would have to get a new strap, but the mask now seals really good.I would recommend to others users who use this mask.

Arrived quickly, very strong
