If you want no-drill blinds that actually stay up, go with spring-tension. Grip-fit clamps slip in South African heat. Magnets weaken over time. Tension systems hold firm on aluminium, wood and steel frames with zero marks. Shop tension no-drill blinds here or read on for the full comparison.

Grip-Fit vs Magnetic vs Tension: Which No-Drill System Works Best?
| System | How it fits | Best for | Biggest risk in SA |
|---|---|---|---|
| Grip-fit / clamp-fit | Small brackets clamp onto the rubber bead of an opening sash | Newer uPVC or aluminium with firm gaskets | Clamps slip on sun-softened rubbers, especially in summer |
| Magnetic | Magnets glued or taped to a steel frame | Steel windows that must stay completely mark-free | Magnets weaken in heat. Wide blinds sag in the centre |
| Tension / spring-tension | Internal spring presses the blind firmly between the reveals | Aluminium, wood, steel and tiled reveals | Very low failure rate when sized correctly |

Grip-Fit / Clamp-Fit No-Drill Blinds
Grip-fit blinds use small brackets that clamp onto the rubber bead of your opening window sash. They look neat on smaller windows and work on most uPVC and aluminium frames with a clear bead.
The problem in South Africa is heat. Clamps slip on older or sun-softened rubber, which is common on the coast. They can also leave tiny marks on the bead if adjusted frequently. We still get call-backs in summer when clamps loosen in Garden Route heat.
Our verdict: Fine for small, light blinds on newer windows. Not dependable for large openings or blockout fabric.
Magnetic No-Drill Blinds
Magnetic blinds rely on strong magnets that stick to a steel window frame, usually with tape or adhesive pads. They are truly non-marking when removed correctly and very easy to take down for cleaning.
The limitation is that they only work on steel frames. Most new estates in South Africa use aluminium, which means magnets are not an option. On wider blinds, magnets weaken over time in summer heat and the fabric sags in the middle.
Our verdict: We stopped offering magnetic systems years ago. Neat for very specific situations, but not dependable for daily use on the coast.
Tension / Spring-Tension No-Drill Blinds
A strong internal spring inside the roller tube is tensioned by twisting the bottom bar. The blind presses firmly between the two sides of the window recess. No brackets, no clamps, no magnets on the frame.
Why tension is the clear winner for most South African homes
- Zero damage or marks. Nothing fixes into the frame
- Holds heavy blinds. We regularly do 2.0 m wide blockout rollers on tension
- Works on aluminium, wood, steel and tiled reveals
- Stays straight for years when properly sized. No slipping or sagging
- Remove and refit in seconds for window cleaning
- Completely child-safe with cordless operation as standard
Our Real-World Experience on the Garden Route
We have fitted hundreds of all three systems across the Garden Route. Here is what we see in practice:
- Grip-fit: Lots of call-backs in summer when clamps slip on softened rubbers
- Magnetic: We stopped offering them years ago because long-term hold was unreliable
- Tension: Almost zero complaints, even on wide blockout blinds after years of use
“If you want true no-drill blinds that survive Garden Route heat and coastal air, tension systems are the only ones we trust on large windows and doors.”

Tension systems leave zero marks. Nothing is screwed, glued or clamped to the frame. You can remove and refit them in seconds without a trace.
