A retractable fall arrester, also called a self retracting lifeline, is usually anchored above the worker: its line pays out and winds back as the worker moves and locks quickly if they fall, while a load arrester does the same job as a backup for a suspended load. Fire Protection System supplies Karam and Delta Plus retractable blocks in webbing, steel wire rope and textile rope, retrieval blocks with a winch and Karam load arresters in Bhopal and across Madhya Pradesh.
A self retracting backup device that stops a suspended load, such as machinery or stage equipment, from dropping if the main lifting system fails. Rated for loads up to 200 kg and offered with 2 m, 3 m or 10 m of cable.
Backup fall arrest for suspended loads up to 300 kg, from machinery to stage equipment. It has the widest choice of cable length among the polymer cased load arresters: 2 m, 3 m, 5 m, 10 m or 15 m.
For heavier suspended loads such as lighting rigs, stage gear and industrial machinery, this arrester halts an accidental drop of up to 400 kg. Cable lengths are 10 m, 15 m and 20 m.
A secondary safety device for heavy suspended loads and structures, rated for a maximum of 500 kg, with 10 m or 15 m of cable.
The highest rated load arrester in this Karam range, with a high strength alloy steel casing and stainless steel wire rope, for suspended loads up to 1000 kg in industrial, scenic and stage settings. Cable lengths are 10 m, 11 m and 16 m.

Sizes: 20m, 30m
A fall arrester with a built-in hoisting winch, so a fallen worker can be retrieved when the block is mounted on a specialised bracket. Galvanized steel wire rope in 20 m or 30 m.
Sizes: 20m, 30m
A dual mode block that works as a fall arrester or, by setting a locking pin, as a retrieval winch for raising a fallen worker. Stainless steel wire rope in 20 m or 30 m, for confined space entry and rescue with tripod and megapod systems.
A self retractable fall arrester with a 4 mm galvanised steel cable and an integrated energy absorber in an ABS case, made in 6, 10 and 15 m lengths and tested at 150 kg so tools carried by the user are covered.
A compact self retractable fall arrester with a 46 mm strap and energy absorber, 2.50 m long, in a protective case with one AM002 carabiner. It is the retractable supplied in the ELARA140 kit.
A light and compact 6 m retractable fall arrester with 25 mm polyester webbing in an ABS housing, with a swivel and fall indicator. Delta Plus states it was tested for horizontal use and lists a horizontal certification to RfU PPE-R/11.060.
Start with the working range, because the line must reach every point of the job without running out. Short webbing blocks suit work close to the anchor: the Delta Plus MINIBLOC AN102 and the Karam Mini Block are 2.50 m with a built in energy absorber, and the Karam Micron Block is a 2 m line weighing 0.86 kg. For mid ranges there is the Delta Plus MEDBLOC AN13006C2 with 6 m of 25 mm polyester webbing and Karam 25 mm webbing blocks from 2 m to 12 m in polymer or aluminium casings. For longer ranges choose steel wire rope: the Delta Plus MAXIBLOC AN100 has 4 mm galvanised steel cable in 6, 10 or 15 m, and Karam wire rope blocks run from 4 m to 20 m in aluminium casings and from 7 m to 30 m in plastic casings.
Next match the line and casing to the site. Galvanised steel wire rope suits general industrial work, and Karam offers 4.8 mm stainless steel wire rope where corrosion is a concern. The Karam Heavy Duty Sealed Retractable Block has a sealed stainless steel casing and stainless steel wire rope for offshore platforms, chemical plants and wet sites, with a 140 kg rated load and lengths of 10 m to 30 m, and the Karam 18 m textile rope block is made for offshore work, acidic areas and high temperature. Where the line can run over an edge, Karam offers a sharp edge tested 25 mm webbing block from 2 m to 6 m, and Karam lists ATEX 2014/34/EU on its steel wire rope blocks and load arresters for areas where explosive atmospheres can occur.
Then check the standard, the user weight and the indicators. The personal blocks are listed to EN 360, with Karam stating EN 360:2023, and the Karam 25 mm webbing block with a steel snap hook is also listed to IS 3521(Part 3):2021. Delta Plus lists the MAXIBLOC AN100 and MINIBLOC AN102 at 150 kg and the MEDBLOC AN13006C2 at 128 kg, tested for horizontal use to RfU PPE-R/11.060, and Karam states an arrest force below 6 kN on its 25 mm webbing blocks. Fall, load or impact indicators on many models show at a glance whether a block has arrested a fall.
For special jobs, twin blocks keep the worker connected while moving between anchor points: the Karam Twin Retractable Block has two 2.50 m webbing lines with steel scaffold hooks, and the Karam Mikron Twin Retractable Lanyard has 1.8 m Dyneema webbing and can be mounted at foot level. Karam retrieval blocks with an inbuilt winch, in 18 m textile rope or 20 m and 30 m steel wire rope and listed to EN 1496:2017, arrest a fall and then raise the worker when mounted on a tripod or megapod bracket, which suits confined space entry. Karam load arresters are made for suspended loads such as machinery and stage equipment, and are rated 200, 300, 400, 500 and 1000 kg.
