What is a universal nylon plug?

A universal nylon plug is a polyamide sleeve inserted into a drilled hole. When a screw is driven into it, the sleeve expands and locks itself against the wall of the hole.

Why “universal”: the same plug works in solid concrete (expansion), in a hollow block (folding behind the wall) and in bricks — without switching product for each base material.

What makes GX-L the leading stone-cladding and block plug in Israel?

In stone-cladding and block-anchoring projects, the plug is one of the most critical components for safety and long-term durability. The GX-L block-and-cladding plug from Adit Ltd. was developed specifically to provide a real answer for every type of wall — concrete, black block, Ytong and reinforced (anchor-grade) Ytong — with field-proven performance and full scientific documentation.

A stone-cladding plug must withstand high shear and pull-out loads for years, under direct exposure to Israel’s harsh climate (heat, humidity, salinity), and perform consistently across different base types. The GX-L plug meets all of these requirements while maintaining unprecedented ease of installation. ADIT Ltd., active in the Israeli market since 2006, has installed the plug in hundreds of projects across the country — from salty coastal areas to the interior.

6 reasons that make GX-L the best block and cladding plug

• PA6 polyamide technology: the body is made of polyamide 6 nylon — a material that combines flexibility with high mechanical strength. Unlike ordinary plastic plugs, polyamide does not degrade when exposed to the alkalinity of concrete and is durable for a 50-year service life.
• Exceptionally high load capacity: in concrete, failure load in pull-out and shear up to 6.2 kN in the M10 size. In black block and anchor-grade Ytong: up to 3 kN pull-out. The data is based on Israeli Standards Institute testing — not theoretical estimates.
• Recognized European ETA approval: the plug carries approval ETA 12/0261 — an international standard that makes it easy to submit insurance and engineering certifications.
• Fast, easy installation: a simple three-step process (drill, insert, screw in). It can be installed by hand without special tools — a significant time saving on site.
• Full universality: a single plug suitable for concrete, black block, standard Ytong and anchor-grade Ytong. There is no need to change the plan according to the wall material.
• SS316 stainless steel for harsh environments: for wet-method stone cladding and coastal areas — the plug is available with an SS316 (A4) stainless steel screw, protected against corrosion, salts and acidity.

Block and stone-cladding plug — material compatibility

• Cast concrete: maximum load performance (up to 6.2 kN failure). The preferred base for primary stone cladding.
• Hollow black block: the classic block application — standard drilling. Suitable for interior and exterior walls.
• Standard Ytong: drilling with a diameter smaller than the plug + 3 additional turns for proven durability.
• Anchor-grade Ytong: suited to the M10 size (service load up to 1.0 kN). The solution for reinforced Ytong blocks.
• Pumice block: tested and approved. Suitable for light cladding and for reinforcing existing walls.
• Silicate and Thermodan: load performance documented in pull-out tests (consultation with an ADIT engineer is recommended).

Detailed load table for a single anchor (failure loads in kN)

All data is based on Israeli Standards Institute testing — pull-out and shear by base type and plug size. The values shown are failure loads; for engineering design an appropriate safety factor must be applied to obtain service loads.

Installation guide — stone-cladding plug / block plug

Installation in cast concrete

1. Drill the hole: diameter matching the plug (for example 10 mm for an M10 plug) with a minimum drilling depth of 70 mm. A rotary hammer drill is recommended.
2. Insert the plug: push the polyamide plug all the way in — this can be done by hand and with a light tap of a hammer.
3. Drive the screw: screw the bolt in until fully tightened (the plug expands and grips firmly in the concrete).

Installation in blocks and Ytong

1. Drill without vibration/hammer action: in low-density Ytong — drill with a diameter 1 mm smaller than the plug diameter (without using hammer mode) so as not to crush the block and to allow a strong grip.
2. Insert the plug: insert with manual pressure. The special outer ribs of the plug grip the block walls immediately.
3. Deep threading: after the normal threading is complete, add 3 more turns beyond the initial grip — this significantly increases pull-out resistance in the block.

The plug that passed all the tests for Israeli and European standards

When choosing a stone-cladding plug or a block plug for a public or high-rise project, looking good is not enough — proven data is required: ETA 12/0261 approval (the most stringent European standard), Israeli Standards Institute testing, video-recorded tests for transparent verification, and ISO 3506-1 testing for the stainless steel versions required in wet coastal areas.

Field experience — in hundreds of projects across Israel

GX-L is not a new product — it is a proven solution installed in the largest projects, from Electra Al HaYam in Bat Yam, the Jerusalem railway, HaShahar tower in Givatayim and Science Park in Ness Ziona, to huge residential and infrastructure projects of leading contractors across the country.
