Available in two lengths to suit different doorway widths:

Why Choose the Screw Fix Flat Door Threshold Strip ?

While our self adhesive 35mm flat threshold is perfect for standard home installations, the screw fix version is the preferred choice when you need a permanent, unmovable 
threshold — one that will not lift, shift or come loose over time regardless of foot traffic.

The screw fix method anchors the aluminium door threshold bar directly into the subfloor, creating a bond that is significantly stronger than adhesive alone. This makes it the ideal choice for:

• High-traffic hallways and entrances
• Rental properties and HMOs
• Commercial and retail environments
• Doorways subject to heavy or frequent use
• Installations over concrete or uneven subfloors

Self Adhesive vs Screw Fix — Which Should I Choose?

Both versions use the same premium 35mm anodised aluminium flat profile — the only difference is the fixing method:

Self Adhesive — quick, tool-free installation ideal for standard residential doorways and DIY projects

Screw Fix — permanent, heavy duty installation ideal for high-traffic, commercial and rental property doorways

Perfect For These Floor Combinations

• Laminate to laminate (same height)
• LVT to LVT (same height)
• Tile to tile (same height)
• Vinyl to vinyl (same height)
• Hard floor to hard floor (same height)
• Any two floor surfaces meeting at the same height

How to Fit — Screw Fix

Step 1 — Prepare the Surface
Clean both floor surfaces thoroughly at the doorway — remove all dust, grease and debris.

Step 2 — Measure and Cut
Measure your doorway width accurately. Cut the threshold strip to your required length using a junior hacksaw or standard metal cutting tool if required.

Step 3 — Position and Mark
Place the threshold strip accurately across the doorway join. Mark all fixing hole positions through the pre-drilled slots in the profile.

Step 4 — Drill Pilot Holes
Remove the threshold and drill pilot holes at all marked positions using the appropriate drill bit for your subfloor type:

• Wooden subfloor — wood drill bit
• Concrete subfloor — masonry drill bit and rawl plugs
• Tiled floor — tile drill bit, drill slowly

Step 5 — Screw Fix Into Place
Position the threshold back over the pilot holes. Secure firmly using the screws and plugs supplied in the manufacturers packaging. Tighten evenly across all fixing points.

Step 6 — Check and Finish
Check the threshold is sitting flush and level across both floor surfaces with no movement. Your door threshold is now permanently fitted and ready for use.

Pro Tip: All screws and plugs are included in the manufacturers packaging — no need to purchase additional fixings separately.
