Quality Spares/Replacement

by Andrew Briggs (08 Jun 2024)

(4/5)

Despite its reputation for being difficult to install this one went in quite quickly with a very liberal spray of silicon and the use of a plastic spatula

Made A Big Difference

by EKBristol (05 Aug 2022)

(5/5)

Strange, but I got the wrong colour although this colour really cheers up the whole surround from the dull grey one and now fits with no edges pulling out. Would be a nice idea if you sold the tools to put it in but didnt try looking for them as thought I had some (none came up as an extra option). Really nice looking now and sets the window off a treat, just have the rest to do sometime.

Great Value

by Jeff james (06 Aug 2021)

Strip was good quality, but you need an insert tool to fit them, which is not sold, so I had to purchase elsewhere. Virtually impossible to fit properly without tool. Needs to be added to stock list!

To Short

Grey insert is to short 23 mm yet rubber window seal long which I ordered but 2 mm short on window rubber which was plenty off seal more than 2 mm short bit funny

Exactly What Was Required

by Mr Davis (27 May 2021)

(5/5)

Exact match for caravan window seals. A bit stiff but heating with a hairdryer made it easier to insert in channel. Windows now look perfect.

Outstanding service

Outstanding service, good prices, excellent packaging and speedy delivery.

Bought Along With 25mm Window Seals

by Rob (29 Mar 2021)

(5/5)

Bought 25mm window seals and these 23mm inserts. Bit worried when they arrived they wear a bit too small. After fitting it would have been impossible to fit 25mm inserts. These fit perfectly.

Finishing Touch To Seal Replacement

by Lunar Owner (20 Aug 2020)

(5/5)

Inexpensive trim used to finish replacement of window seal on a Lunar caravan. Grey colour matched original inserts perfectly. A bit fiddly to slide into the rubber window seal, but with a light spray of silicone lubricant all round the seal faces, and using a blunt screwdriver to tease the insert in, this was easier than I feared. Would certainly recommend.

Shrunk Insert At Window Corners

by Happy caravanner (18 Aug 2020)

(5/5)

Cut off the distorted and hardened insert at the corners. Measure the remaining gap to fill and add extra 50 mm length of new insert. Fit new insert with a 25 mm overlap each end. No gluing or welding required.

Basically does what it says on the tin!
I had to replace the old one due to shrinkage. Service was great considering we are in Lockdown.

Just The Job.

For new widow seals finishes it and tightens the seal excellent.
